I've got no trouble with immigrants, whether they be Mexican or otherwise. I just don't like the fact so many come here illegally. If it is done right, they're welcome here. I understand that most are trying to make their lives better, but the first thing an illegal does in the US is break the law. That doesn't show much respect in my book.
Another perspective is to ask why Mexican citizens don't address their own problem. Instead of running away from a lousy, corrupt government, maybe they need to face their problem and do something about improving Mexico. We stood up for ourselves 230 years ago. Maybe it's about time they did the same thing.
