It apparently went over your head, then.  I pointed out that America allows countless dark-skinned people from India to immigrate here.  Thus, our immigration policy is not racist.  Further, insofar as the proposed legislation affects hispanics, I should also point out that hispanic is not a race; that the proposed legislation affects white hispanics as well as non-white hispanics; and that the discrimination has to do with language and culture --- thoroughly permissible factors to be considered in setting immigration policy.
