I had my first taste of this mentality first hand last week. I was waiting to pick up my daughter from Kindergarten and I always make small talk with another mother who waits. She is 2nd generation Mexican/American. She proceeded to tell me that she had asked the teacher if she needed some help in the classsroom and the teacher said "No, I think I am ok right now". To which she replies to me, "She just didn't want my help because she is a racist and doesn't like Mexicans." I thought that was odd, but hey whatever.
So about two days later she was telling me about her neighbor complaining about noise her family was making. To which she says to me (you guessed it) He's just a racist, who doesn't like Mexicans...My point-how are we ever going to undo this mentality?
