I agree with you and have seen proof of it.As I said on another thread tonight,you should hear what many people in Arizona say about Mexicans when they've had a lot to drink,it can be pretty nasty.
Usually the remarks are triggered by having seen or been in an accident with an "uninsured driver",having their house broken into,waiting in line anywhere while a long transaction took place with a clerk who only spoke english and a non citizen who spoke no english,went to an ER that was packed with non citizens etc. and so forth.
Sometimes the person is an Arizona born Mexican but usually it's just a person who works with,lives close to,went to school with,goes to church with and generally counts many Mexicans as good people and is friends with at least a few of them. Under normal circumstances they would never say anything unkind about Mexicans because they don't even think it. Yet occasionally something as described above will trigger a diatribe that is truly ugly.
