A lot of people here are saying it's because they're jealous of our features but I highly doubt that's the case. The problem is diversity. Different ethnic or racial groups cannot live together. If this whole "muh features" theory was true, why do AA's bully Africans who look just like them? Same thing with Mexicans and Central Americans. They always fight it out in Texas. Mexicans and Native Americans have had school riots in New Mexico and Arizona. Or how about Dominicans vs Puerto Rican's vs Jamaicans in New York? Haitians vs Cubans in Florida?
Diversity is a very bad thing!
Some diversity is good, like if w productive migrants move to Somalia and help build it.
Some ethnicities are cool like Japanese, others like Somalis and Pakis attract conflict.
