Who is accusing Christianity for anything? China wasn't even Christian at the time.
AGain it is debatable but pretending Muslims are innocent while accusing christianity is just ridiculous.
And do not make me laugh. China is shitty yes but only Christans and Muslims did fought brutal wars and crusades in the name of Religion. Also if you believe Slaver in Muslim countries did not exist I just think you need to look this up. It still exsits today. Just now there was a huge case in Lybia and African slaves being sold of. And now guess who it was?
And my true Colors would be. Religion is bad. Any form of Religion only led to war. Today almost every conflict is based on religion as well. So yes my true colors would abolish religion from earth and it would be a much much better place.
Instead of trying to find information to fit your narrative you should start asking questions why you think that "Muslims are probably Number 1 at oppressing others through out history" and what led you to make that conclusion. Whatever it is start questioning those sources. It's not like information is difficult to get. Even Wikipedia is decent source.
