It's not your business what language they speak at home....and it's not their business what Brock says, either. The incessant sniveling coming from these so-called "Hispanic leaders" (aka illegal alien cheerleaders) is getting to be pretty annoying of late.
People like Brock have been irritating for years. The Conservative attempt to run off Hispanics (and other minorities) seems to be quite successful.
The Liberal attempt to pander hasn't been so successful though. It's easier to insult than to pander.
