He's not, but you've demonstrated a pretty impressive amount of your own racism and ignorance in a single sentence.
☑ distorting the history of slavery (Muslims had slaves, but it was widespread everywhere except China)
☑ the usual nonsense about Aisha bint Abu Bakr
☑ out-of-nowhere assertions about "warlords"
☑ "Islam can be described by its worst moments but Christianity shouldn't be blamed for colonialism"
☑ don't want to learn/read anything conflicting with what your parents taught you to believe
Furthermore, when did I excuse Christianity? You're just doing what-about-ism to justify your islamic apologetics right now. I am neither muslim or xtian and never made any of the above claims.
