Are you accusing me of racism, jackass? YOU just expressed your concern over non-whites coming here, so you're clearly a racist and therefore not to be considered as human with any of the considerations accorded to such.
They work. Do you know citizens who want to pick crops? I've yet to see any blond hair in the fields in California, for some reason. In the 30's, yes, when the Okies were doing farm labor. But those days are gone.
I'm of European ancestry, fool. I've lived in Central America. Language is not a barrier for me, since I've spoken Spanish since childhood. Non-whites don't bother me, since I'm not a racist white-right piece of shit like you.
