........... and third parties only want the other two's power, since we are being cynical and demeaning. You can't say everyone else is misguided in saying everyone else is misguided. Circular argument.
As far as conservatives go; there are some good Republicans, there are some bad, there are some good libertarians, there are some bad. the difference is where they fall in the spectrum, but the ideology is/should be the same root. Liberals? well, i disagree fundamentally with their ideology basis so I can't really agree with much, if any, of their platform. Don't hate them, just think they are wrong.
Bottom line is people need to know why they believe in what they believe (not by feeling, mind you). Then they can reasonably debate. IMO, most folks don't really know their basis for belief. It usually stems from parents, culture, media, just about anything. Not that those are necessarily bad, but they don't really challenge or think things through themselves. When they encounter something they can't easily rectify they default to "how i feel" about the issue. That is where most of us screw up. It is an exercise in diligence and perseverance that most folks are to lazy to push through.
