klan vs. mexican all the way.
The reason I like this one is that you also have a social domination, as well as probably a language barrier. Not only is the victim helpless to verbalize her protests, but she and everyone who looks like her is defenseless to do anything about it after it happens.
And for the record, I'm Nicaraguan, which is kind of the same as Mexican except our food is better and we don't do any of that Dia de los Muertos crap.
