And perhaps not. Many native born US Hispanics are as much against illegal immigrants as anyone else. Some more so. I still remember how shocked I was to hear a friend, herself only first or second generation Hispanic and very "Indio" looking, say something about "those d@%n Mexican"
That's new to me, as well, hearing native born mexicans deride 'wetbacks'. Turns out the nouveaux are cutting into their state bennies.
You know, as I was writing that I was thinking of my D-i-L's parents and that they have the same attitude. Second generation Americans, the grandmother is a charter citizen of the State of Arizona.
So, yes, it could easily be as you suggest.
I think that most hispanics don't support the illegals. I think that their leaders use the race card just like the black leaders such as Jessie Jackson.
The leaders are the racists, they use it for their own power. Most hispanics I know want to border closed.
