Being a native Texan, and watching my parents' neighborhood go from all white to majority Hispanic, I think I know a thing or two about their impact. At first my parents were very worried, but now feel fine and wouldn't think of moving.
I wouldn't think of moving either. My town has been multicultural since I went to school here in the 'fifties, with no problems, it was a wonderful place to grow up. There were immigrant Slavs, Italians and Poles, there were black Americans, Mexican Americans, Japanese Americans, and American Americans, we loved it. My family since has become a bit multicultural, no problems.
Again, what we are talking about is ILLEGAL IMMIGRATION in the millions, and their drain on our social services, the bills being paid by us. Where is your problem in understanding that? We have valid complaints of being fleeced of our paychecks with our government applauding it. It's not racism, it simply has to do with invasion.
