My personal opinion (as a dispassionate atheist) is that religion isn’t the problem with human nature. In the U.S., for instance, we have some Christians who have strayed so far, I don’t get how they’ve even seen a Bible verse. But also, basically every major Civil Rights leader was a Christian preacher or woman of faith. There are similar situations everywhere. There’s Buddhists who are so non-violent they wouldn’t kill a fly and other “Buddhists” who commit genocide, which doesn’t even make fucking sense.
So, my view of religion is that it’s mostly not the thing to focus on. People can be organized for good or evil and there’s plenty of secular things where people define an identity. I suspect if religion never existed, we’d have all the same problems. I mean, we have soccer hooligans and it’s not because people object to 22 people getting some exercise on a lovely afternoon. (Or a miserable, rainy Wednesday night in England.)
