La Raza is a racial supremacist group in california, what are you talking about
but lets go with that. we can't stereotype mexicans by all of the bigots and anti-black gangs in their country, but we're supposed to believe mexicans all share solidarity with blacks because of a comment they made about ferguson?
any outside group will point out the blatant white supremacy against blacks to show chinks in americas armor.
also, Blacks make up ~2% of the population in germany, most of which has experienced racism. if 40 million of us suddenly showed up on their door step, it would be a much different situation.
