See, I think this is what they're talking about though. I hate Christianity. I was raised Protestant and because of other factors in my life, Christianity effectively ruined large swathes of my lifespan. It's still an active threat to me, and likely will be for my entire life. I'm likely to be a fairly stringent atheist forever.
All that said, edgy internet atheists are one of the most annoying archetypes to run into online. If even a whiff of a religious topic comes up, they pounce and nip and bark. They satisfy almost every stereotype the religious people have of them because they often seem to delight in the cruelty of knocking on beliefs. Like, my whole top comment still being relevant, religion has a reason to exist. It gives people feelings of hope, love, and belonging. Anyone who has experienced a lack of those can understand why people fall into religion and why it's like any other addiction.
I'm breaking one of my rules right now, talking about religion on social media, but I figured the "meta" aspect of this thread would make it productive. I hope I don't regret it.
