Overpopulation? Where?

I'm so sick of people complaining about overpopulation. Apparently, the people who complain about this have never been anywhere outside Calcutta and Mexico City. Having driven across our great land on several occasions and in various directions, I can honestly say that there is far more uninhabited land in America than there is inhabited land. Most of this great country is completely blank. Move the homeless out there, or something. Seriously, we're occupying about 2/5 of the entire country. Plus, we're not the only country with that problem. I'd venture to guess that Japan is the only nation on Earth that should actually harbor a legitimate concern for overpopulation. For everyone else, there's plenty of room. I, for one, want to see people more concerned about the overliberalization of America. Hey, if we slaughter all the liberals, we'll have room for 51 million more people!
