Words are inadequate

I have often felt like the thrust has been to open and warm conservatives' minds to liberal approaches and vocabulary, but not the other way around.

Ah, the old "you must be tolerant of intolerance or else you're intolerant" dodge. Which, you know, no, but thanks for playing.

That tolerance of conservative ideas would be akin to moving backwards and not simply respect of a different perspective.

Show me. Seriously. Name me conservative ideas that aren't fundamentally opposed to progressive principles and that don't get a fair hearing and tolerance in the liberal marketplace of ideas. There can be no meeting of the minds between people who think that, say, the religious (conservative Xian) definition of "marriage" should be the state definition, or that a clump of cells the size of a pinhead has more rights than the woman whose body it occupies (unless said clump of cells is part of a fertility treatment, in which case throwing it out is all good). Apart from things like that, what have you got?

I think it likely that no two people who assign themselves one of these labels ascribes to the exact same set of ideas, anyway.

In the strong case, this is a tautology: of course no two people have the exact same opinions on such a wide spread of matters. In the weak case it's inaccurate, because people who believe generally the same thing and cooperate towards generally the same goals end up with generally the same labels, and are generally happy about it. Except in cases where their goals end in disaster, of course.

I'm willing to grant that the "conservative" tag is an odd duck because of the modern Republican union of the religious right and the tax-cut zealots. On the other hand, conservatism can never fail, it can only be failed.
