Why do anti-immigration folks ignore this kind of illegal activity?

Now that you made this question, people against illegals say they know that. Why didnt they mention that they knew it before they post Mexicans abuse this and mexicans do that? The keep ranting about mexicans, mexicans, mexicans. Yes we do acknowledge that their is a greater amount of mexicans that are illegal. It is not being denied. The only thing this question is trying to prove is that many anti illegal groups target their hate againts mexicans. They generalize it. If your going to be anti illegal then at least admit that theirs illegal immigrants from all over the world.
