Indeed. The South gets a bad rap. Interestingly enough, there's a lot more KKK, Neo-Nazi, and Black Panther-esque communes on average per acre in California than there is in any of the individual southern states. But people still listen to Seth Macfarlane's "south" jokes and take them to heart like he's honest Abe.
Some of those violent racist groups in California are hispanic, or more specifically latino:
Nation of aztlan (as described by the Anti-Defamation League, that tracks antisemitism)
MEChA (note the stick of dynamite in the eagle-claw of their national symbol. Nope, nothing violent about these guys...
But y'know, again, stereotyping of whites, and angry scapegoat rhetoric that incites violence toward whites, is not classified as racism, in the politically correct world we live in.
