We've discussed your disdain for actual mexicans before. I'm not gonna go dig it up, but you did admit to holding them in low regards because as you said, they treat you the same way. Again, if you claim you don't hold that position or that you didn't say that, cool.
And, I did get that feeling from one sentence. Here's the logic: folks in this thread are saying were racist down south, someone says you're racist, too, since you don't lie mexicans from mexico.
You then attempt to differentiate by saying "it's cultural, not racial'. If your not differentiating to say one is "better" than the other, then just what are you differentiating for?
And, if you're not saying that, then you are in agreement with me that your prejudice is no different then their racism - and you have no room to cast stones in this here discussion.
