They would get a nasty surprise indeed, considering the fact that these blanquitos aren't known for putting the other cheek to begin with.
Mexicans have been attacking minorities for no reason to. Especially blacks and asian americans. Lets not sweep under the rug the racial tension between mexicans and asians in the west coast. The Mexicans were very racist and vice versa to the asian people which resulted in a lot of dead members from both sides. And the white/mexican immigration tension in the southwest also.
