I have already damaged Hogwarts' lore by including literal porn elements in it. You seem slightly hypocritical in how you pick and choose what needs to be included, but you need to realise that the game simply doesn't revolve around your tastes. It revolves, mostly, around mine. I find Old Testament and generally occult elements (not Christian elements, there is not one excerpt from the Bible lol) interesting, so I include them in the game to an extent, but the idea that I am proselytising when most of the comments and ideas about religion are downright heretical, is actually just silly man. I simply combined a lot of elements that I liked, including among them these occult elements, school environments, magic, etc. The compatibility is so-so, but Christianity in Scotland around the time Hogwarts was built still included a lot of pagan elements, including from viking influences, so I do not think it is that far-fetched that it had a presence there IN THE PAST, which was then entirely excised around the time of the witch trials etc, only to now, finally, in the modern day, make the smallest of returns, with that SINGLE priest character.
I also cannot see how you feel that they are overwhelming. Most of the religion-related stuff, from the church, to the Old Testament scriptures, to the party with the literal evil God worshippers, were all added in a SINGLE release, most of which I wrote while sick with covid and so felt especially appealed by the these slightly feverish elements. The conversation between Ron and Hermione has absolutely nothing to do with religion (or at least it wasn't intended to, but I seriously cannot stop you from interpreting it however you wish to, even if it's really annoying to hear your own message twisted), and also, the "message" during it seems to be the exact OPPOSITE of what I have to hear from most of the retarded Christians when they try to force their faith on others, where the arguments mostly revolve around logic and muh ontological proofs for God.
But if you absolutely do not like religious elements, I strongly advise against playing it, because the next couple of releases are going to feature a lot of Druidic / Celtic religious elements. That said, your game idea does sound pretty interesting and I wish you the best in creating it. I do wish that you would at least try and seek help for some of the things I mentioned because, while I am not a psychologist, I do recognise some of the paranoia and the strange obsession with finding patterns where there aren't any in myself. Good luck
