Even if you were right - which you're not - the ground rules for this movement, and the basis for Aztlan, is "(A) Movement, which advocates on behalf of 'indigenous Americans,' or those people without European ancestry."
That would exclude Mestizo, and that would be more like 97% of the population.
Check your facts before saying I’m not right (and see post #30). Spaniards are much paler than these guys; they are American Indian who happen to speak Spanish, like our full-blooded Indians speak English. However, I agree that if they had to prove NO European blood whatsoever, that would be hard to do.
