*catholics you mean

they purged a lot of things, the cathars, they were involved in instigating the crusades, the spanish inquisition, in modern times one i never heard of was the conspiracy theory stuff about freemasonry, which is actually just a thing along similar lines as rosicrucian and other scholar-focused studies of spiritual texts. the catholics tried to eradicate the book of enoch, even though it appears multiple times in the bible, and is even basically quoted by most of the more famous statements of jesus, the whole thing of "word of god" was done by them as well, where in fact before the formation of the roman catholic church, there was very wide diversity in doctrine and practice of christians. the gnostics, the essenes, the cathars, and a whole load of other crazy things. like the bogomil in the balkans, that's actually where the word "bugger" comes from. and of course such a list of crimes would need to include the pedophilia of priests, the frauds of certain nuns, and other similar scammery.

not like any religion is free of this insanity. ISIS, ISIL, the muslim brotherhood, the buddhists setting themselves on fire, the falun gong thing, the sanyassins and osho, etc etc etc. but i just wanted to focus on the fact that most of the crimes associated with christians relates to the catholics. and in more recent times, the crazy evangelical shit in USA is pretty much awful as well. the branch davidians...
