Theological disagreements, such as the nature of Jesus' divinity, the proper relationship between Christianity and Judaism, what even is the Trinity, etc.
I know. But the person above made its point that the christians only eradicated other cultures/religions, when they were cruel and sacrificing humans. So my point was: no, obviously not.
"this is also how the early Christians felt, which is why they eradicated Roman paganism"
does sound a lot like it to me. Because why make that argument at all, when they in fact not just eradicated the pagans? (which just means non christian religion btw. they were and are quite diverse)
