Good grief, when I was in college (not that long ago), they needed to truck people in from two counties away to have a decent-sized "rent-a-mob" for their pathetic little demonstrations. And most "Latino" students just LAUGHED at them. About the only folks who went to those meetings were the Latino equivalent of the white trash college student who thinks Calculus is a Zionist plot to oppress him.
No more than I think that the KKK represents all white people. However, the KKK has been (rightly) marginalized and ridiculed by the media and hounded by Federal authorities. MEChA an La Raza, on the other hand, are given free reign to spout off with their anti-white, ant-U.S. sovereignty, reconquista dogma.
