What I consider it is irrelevant to this discussion.
Seems to me you are hung up on the extra-constitutional argument that since Mexicans in Texas pay Texas taxes, that Mexicans should get instate tuition.
It's a cr*p argument.
If they meet all the requirements I'm for them paying instate tuition.
They have already been given "free" HS education; why object to them paying for college?
Comprehende?
