Is it possible to look at Mexican culture and not like what you see (and not want to import it here) without becoming a "racist douchebag"?
Is it possible to dislike any culture (except ours, of course) and without becoming a "racist douchebag"?
Of course.
I'm not a fan of most any culture other than American, there is practically nothing about Mexico that I like and I'm sorry that a lot of the western states have become overun with illegals.
That being said, if Tancredo went around calling for the internment and deportation of illegal and resident alien Muslims I could support him, but his obsession with Mexicans makes him racist in my opinion.
