Of the major ones, unironically Protestantism.
Prot central doctrine is that all you have to do is believe to get into heaven, which
1) means that Prot religion is completely fucking pointless because it has no precepts other than “be yourself and believe ;)” which would in and of itself send these people to hell by the standards of any other religion and also is used to justify degeneracy.
2) because of this prot religion also has 0 utilitarian purpose. Prots cant build pretty churches because they’re unnecessary, they can’t justify moral claims because they’re unnecessary, they can’t even say anything about God because “you just have to believe ;)”
It’s literally a religion for 5 year olds and Americans. Don’t get me started on the megachurches and commercialization.
