I'm calling him delusional for speaking on others behalf, not for finding meaning in whatever he finds meaning in

I don't know why you think the number of followers gives religion any legitimacy. I'm sure your ancestors thought slavery was A okay or treating women as property was the right thing to do, and they would have likely been part of the majority back then, history still remembers them for the barbarians they were, just cause a lot of people hold some superstitious belief means nothing to me. There's a reason people are becoming less religious and church attendance has been dropping on average decade after decade, I don't see that trend changing direction, at least until WW3 or climate change fuck up society enough that praying for magic man in the sky is the only thing left for desperate people to do, not that it'll lead to anything.
