I'm not sure it's silly to acknowledge that people tend toward one philosophical POV or the other. If it's the name "conservative" or "liberal" that bothers you, I can assure you that if those words disappeared tomorrow, we'd have two new words tomorrow to describe what are obvious differences.

Just because one differs in a point or two...

1. they're still likely (as donuel just associated himself 98% with bobert) to associate more strongly with one side or the other because...

2. the reasons, the philosophical underpinnings of why one leans one way or the other, will still be there no matter what you call the rose. This isn't a cart-pushing-the-horse exercise. We don't choose to be conservative or liberal because we like the name -- the name merely points out that there are two BASIC ideas driving modern politics.

or not.
