I’d like to answer the OP.
I used to be an angry atheist, or an anti-theist. Not anymore, because I don’t give two shits. But I was for a time a few years ago. And this happened after I became an out atheist. The reason was simple: theists were dicks to me. When I became an out atheist I expected it to not be a big deal. Spirituality was a personal matter, and no one else’s business. But then I was harassed, my tires slashed, I was physically assaulted, and I keep getting pulled over by cops who see my Darwin fish. I won’t say this is all theists, but it does happen. And it does engender some resentment and anger.
