I'm in the military. I've met Democrats (usually junior enlisted who haven't learned better yet), but I cannot recall EVER meeting a liberal.
There are some Democrats with conservative leanings - usually because they don't know enough about economics to understand that Democrat "compassion" is just hogwash. But the democrat base is Liberal - and Liberals ARE ashamed of America & opposed to the very idea that our values could be judged superior - unless, of course, that 'value' is gay rights or anti-tobacco.
