The simple truth

[Esquilax]

Ok, rather, the atheist I've encountered, though that may be a small sample

Okay, so the majority of the atheists you've encountered have been angry and insulting when you've talked to them, and for some reason you fail to consider that the other common element of those interactions- you- might be playing a part in that?

Let's be clear: this is a small sample size that, judging from your interactions here, you've intentionally manipulated into being angry by how uninterested you are in whatever they have to say, and how willing you are to strawman and misrepresent the things we believe in in order to get a mistaken upper hand.

Any insults you receive are a very natural human reaction to how you behave. It's got nothing to do with being an atheist.
