The Mongols are Asian and slaughtered Europeans plus had European slaves. The black death came from Europe; and The Mongols gave the black plague to the Europeans on purpose by throwing\shooting and catapulting dead plague bodies into cities.
Only a hand full of Europeans were even left after the plague... but some how the population bounced back.
Japan committed mass murder against Europeans on death marches and concentration camps. As well as millions of Chinese. The Chinese are still mad at Japan and their is anti Japanese sentiment among many Chinese.
Islamic people killed and enslaved Europeans... esp. the Slavic people. Ottoman empire for example. Correction: still kill and enslave today - (literally)!
Also add the genocide in South Africa. Europeans will be gone soon. Do the math.
I could talk about Asian and African genocide like Rwanda, pol-pot, cameria rouge ect... but that's an endless list. Anyway I am pretty sure sure China has one of the highest... as mao (if i'm not mistaken... killed 70 million) Over all... I say the Mongolians were the worst... since it's a miracle any Europeans survived at all after Mongolian slaughter, slavery, oppression and the black death brought from Asian and purposely given to
Europeans to commit genocide.
Also, 911 and all terrorist attacks are genocidal in nature; and they make no qualms about it.
Japan's goals in 1942 were genocidal in nature; and they considered Europeans inferior sub-humans to be exterminated and enslaved.
