The question: Is there an atheist schism?

Atheism itself, atheism as such, isn't and can't be a movement, because atheism is, at a minimum, simply non-theism: non-belief in any god. Mere non-belief in any X can't by itself constitute a movement, because it's merely an absence (or at most a refusal) of belief. If every absence of belief in [your chosen belief-object here] amounted to a movement, the traffic jam would be a nightmare. A belief about the world shouldn't necessarily commit us to political action – we have to be able to say "No" to affirmative beliefs about the world without thereby signing up to a campaign. We need to be able to make such choices more freely than such a requirement would allow.

Atheism can however include something like a movement, of course, as can other beliefs and non-beliefs. Some of the disagreement among atheists is around this issue. Many atheists want to be able to be atheists without being dragooned into some boring noisy unsubtle bad-tempered "movement". Many other atheists want to be able to be overt explicit unbashful atheists without constantly being told to be more euphemistic or evasive or respectful or just plain silent by other atheists, who surely ought to know better.

Well?
