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.
If you'd pay attention to what Tancredo has consistently and repeatedly said about both borders and the INS you'd know that he has. You sound a lot like Jesse Jackson calling other people racists but exempting himself from the same label. By the way, you forgot to mention that he hates Canadians too.
"The number of violent encounters along our border is increasing, creating a need for immediate action on the part of our government and the government of Mexico and Canada," stated Tancredo.
