"Atheists, please stop _____"

  Dear atheists of the Internet,

the following are things I think don't help your arguments and only serve to derail or degrade conversations with theists (or other atheists.)  This post isn't necessarily suggesting that these are common among the atheists of the Internet........... but some of them kinda are.  However, the spirit of these complaints apply towards theists as well but I'll write the theist crowd specifically another time.  I understand that the topic of theology can evoke much passion from some individuals but everyone should should put forth their arguments as honestly and consistently as possible.
  This list isn't written in any particular order, just the practices themselves with no indication as to their perceived severity in comparison to one another.  I am also not writing any in-depth, nuanced expoundings here, just a few thoughts.
  Many of these things are essentially "apply sound skepticism." However, the main message, really, is to stop saying some of these things that just propagate progress-impeding biases.

Claiming the atheist presence in the prison population is only around [crazy-low %]

"Who keeps bookmarking Ezekiel 23:20?"

  The American prison system is bonkers and filled with plenty of people who probably shouldn't be there.  It's a broken system employing broken methods pumping out broken people- not an ideal place for insight concerning such philosophical issues.  That's not to say that we can't learn interesting things about prisoners and the population as a whole, but many people who are incarcerated would rather not be and there's a lot of motivation to say/profess things that may potentially alleviate or reduce your time behind bars.

Debating whether babies are/n't atheists

Now this baby is ready to draw some truth tables!

  What babies may or may not believe is irrelevant. Babies aren't capable of making informed theological decisions. They just want someone to keep them alive, comfy, and happy (don't we all.)
  They don't have object permanence and can be convinced that you've stolen their nose. They are dumb.

  Treating fundamentalists/literalists as if they represent Christianity as a whole.

Hurricanes, earthquakes, and AIDS are just God reminding us he loves us!

  There is certainly no shortage of religious people with especially awful beliefs and means of expressing those beliefs.  However, to make the Westboro Baptist Church the representative of Christianity in your mind is to be ignorant of how most Christians actually are.  The moral Rorschach test that is the Bible can be used to personally justify almost any stance or action.
  Get twenty Christians in a room, talk to them long enough, and you'll likely be exposed to twenty different versions of Christianity/God with many of the professed beliefs being completely incompatible.  ISIL doesn't represent the Islamic community, WBC doesn't represent the Christian community, ask the individual you're talking too what their beliefs are. and why.

Exclaiming religion is "like a virus."

It appears you have a bad case of toxic self-righteousness.

  I get the sentiment behind this one (and many of those sentiments hold at least somewhat true) but "religion is/spreads like a virus" is not only unhelpful, it's inflammatory and uncharitable.  There is a multitude of ways people become theists just as there are multiple ways people become atheists, agnostics, whatever.
  Many of the mechanisms within the sentiment of the label"virus" apply to a lot of other social ideas and movements. So unless you're ready to follow such loaded language with qualifiers it's probably best to just use a different word.  It fosters an incorrect "infected/uninfected" notion concerning how people develop opinions.

Saying religious people are brainwashed/stupid.

Faith: one-size-fits-all

  While many people are religious as the result of indoctrination or being raised in a religious environment, some folks become theists later in life because they've been convinced to do so.  Saying they could only have that position because they were "brainwashed" or "stupid" is similar to the "virus" platitude above, inflammatory and uncharitable.  
  Some of the greatest minds in history were theists, there's no reason to assume someone is unintelligent or incapable of making their own decisions on the basis of their theism alone.  I think a lot of people hold supernatural ideas because they partition off their religious beliefs and don't open them up to nearly the same scrutiny and standards as other beliefs they may hold.  Confirmation bias, illusory correlations, misplaced confidence, sheltered lifestyles, bad reasoning are all always a risk- regardless of your stance on the god question.

Name-calling.

"Dumb noodleloaf!"      "Snot-nosed troll!"

  Making it personal, calling people awful things, abusive/bigoted/accusatory language, these things can drag a dialogue downhill mighty quickly.  If you can't get a point across or not handle disagreement without making things ugly then you are a poor communicator.

  I'm not saying emotional, coarse language and strong opinions don't have a place in a discussion.  However, if the aim is to correct misunderstandings, acting like a total bastard isn't a productive way of going about such.  Argue points, not people.

Those damn memes!

^click to see full-size^

  1)  No, they were not all atheists (several were theists, but in a manner that would totally piss off most Christians nowadays.)  Also, their being atheist is irrelevant.  Yes, plenty of great, influential people would identify themselves as atheist, agnostic, or an apatheist (sometimes by way of deism) and it's irrelevant as to the truthfulness of theism or the claims these individuals made.

  2)  There were scientific advancements in the feudal times and also this meme has no useful indicators of measurement or how it is arriving at such "figures."  There were also institutions of learning and teaching that were funded by the church.
  Also, this meme ignores the fact that history was occurring outside of Europe back then.  For some cool reading, look up the "Islamic Golden Age" and see some of the amazing advancements that occurred while Europe was rediscovering how neat theatre is. 

  3)  Aside from this being a photoshopped image (and of incorrect era/nationality space hardware) this quote is disputed and was never verified by Yuri Gagarin. 

  4)  Zeitgeist... don't reference it.  That film (I'm not even aware of what the other movies talk about and I don't really care) has too much speculation and flimsy nonsense in it.  Friends don't let friends share Zeitgeist memes containing claims that are often dubious at best. 
  (+ Yes, Jesus' story does indeed share a great many parallels with other figures from other religions. No, in many ways not like this reductive meme.)

  5)  Plenty of productive scientists and lovers of science are theists. A scientists' a/theism is irrelevant as to the truthfulness and usefulness of their claims.  Also, that image is just spiteful and mean.

  6)  For the most part, I'm not a fan of memes that use pictures of starving, mutilated, and/or afflicted people to advance a point.  It's an attempt at emotional manipulation (even when accompanied with actual data) and, at the very least, potentially distasteful.

  My suggestions for making memes, should you ever feel inclined to introduce a new snack-sized opinion/fact to the Internet: 

• When you can (and please, try your best) include, within the image, references and sources if the meme is making a claim about history, science, a study, polls, ect...  Provide a means for people to hear/read/see the recording/quote/study for themselves. 
• Always hesitate to assign intent, especially when details are speculative or inconclusive. 
• Reconsider any inflammatory or strong language, evaluate how such wording could affect circulation and reception.  I'm not necessarily saying you should censor yourself, just that you should consider effectiveness when considering style.
