I’d suggest going back and rereading history with a more open mind to the truth. Overwhelming secular humanism in the modern West is why we’re where we are currently and their intent is to eliminate Christianity and welcome in the current gender confusion and all the other alphabet nonsense. Just because humans are fallen creatures prone to sin, doesn’t mean Christianity is wrong or has caused any of the examples you threw out. And without it, I shudder to think where the world would be.
I recognize terrible things have been and are still done in the name of Christianity, but adherence to Christianity caused the Western world to grant rights to women and see them as equal partners with men, finally free the slaves (way later than it should have happened), recognize the inherent dignity of each person, value human life, value the nuclear family, value classical education (schools in NA were all founded by Christians), value individual liberty and freedom from oppression, etc etc.
