My wife and I are both liberal. No, we don’t consider ourselves to be “socialists.” In our experience, we find that many people don’t really know what they are talking about when they start talking about socialism, anyway. And far too many who want to overlook the fact that America doesn’t have a purely capitalistic system, as well.
I think you can relax with your worries about America becoming “socialist”. Fear is the problem in our society, and we have a great nation, if people will let go of being afraid of everyone and every thing, and seeing the boogeyman behind every bush.
