I think at least for people that grew up in the US, being surrounded by the consequences of capitalism and religion intermingling, it's cathartic to just tell these people they're absurd and need to shut up. Like if your parents or teachers were religious and used that to excuse being abusive. For me it was that sort of thing that pushed me towards edgy atheism, I was already atheist in the sense that no one had taught me about religion and it didn't apply to me till I was like 12 when a stepparent put me in a church program, so I don't recall ever having believed it or even considering it as something that could be true. Come to think of it I don't remember actually believing Santa either, damn I wasn't a very whimsical child. Anyway, what got me away from Internet Atheism is those people were homophobic and used their hate of religions as an excuse to just be racist towards people in the Middle East. Anyone else remember the "well if 1 in 10 M&Ms were poison would you eat any?! No, so why would you let in a Muslim that might be a terrorist!" I remember that being shared around by people on Facebook. I'm on a tangent now but another thing that pissed me off was, I live in the southern US, but the moment Obama got elected and it seemed like being gay was normalized every gay dude I knew immediately cashed in on the fact that they were still white and men so they became massive racists and misogynists, and of course obnoxiously atheist. Was wild to see happen in real time.
