Imagine if a religious person suggested making atheism illegal. Yet atheists want to criminalize religion.
For what it’s worth I don’t think religions should be banned at all, it’s a key part of people’s view of themselves and of the world. It’s intricate to people’s character, even non belief is intricate to that persons character. Also it wouldn’t accomplish anything - people who are so inclined would just find something else to use to justify their hate.
