Not a big fan of religion but there are plenty of pastimes that don't appeal to me. Harmful to society? That would depend on what you want in a society and what you think they do to fuck it up. But society is consensual. Not up to me personally or anyone else. But go ahead and make your case.
What kind of society do you want? Who agrees with you? How is religion harmful to it?
