"Rush fans who stand no chance whatsoever of ever hearing arguments like mine coming through their radios"
is because most people who listen to talk radio are able to be entertained by simple audio stimuli, without having to resort to "eye candy". May be faulty logic, but I think this is an indicator of relatively high intelligence. Ergo, not many DemonRats listen to talk radio, since they are relatively dense.
On a related note, you ask for concrete definitions of "liberal" and "conservative" on your profile page. That's impossible. They are abstract terms, meaning something different to different folks. Ask a black man what "justice" means, you'll get a distinctly different answer from when you ask a white collar white dood.
If there was only one definition for anything, there wouldn't be umpteen religions all reading the same Bible. But here...here's my definitions: Liberal: A person who believes in an idyllic, fog-filled, dreamy world where everybody skips around happily, singing along to happy tunes magically piped into the scene from above. This genre of humanity disregards the world around him/her as reality, prefering to harbor their "Utopia" fantasy. They don't appreciate working hard, and enjoying the fruits of their labors. They prefer to punish superlative examples of their race by taxing the crap out of the succesful, and loathing them anyway.
On the other hand, we have 2)Conservatives. These fine folks wish that #1 would get the hell out of the way so they can work hard, be succesful, and go buy that bigger house. They feel that they are the best at deciding how they live, and don't need no stinkin' government to dictate minutae to them every day, ever way. I could probably go on forever, given the nature of the discussion, but that's the gist of it...
