In my lexicon, the opposite of "liberal" is "intolerant..." (troll)

Exactly so. But I've noticed that, even in this thread, lots of people have been using the lower case, writing "liberal" instead of "Liberal" and "conservative" instead of "Conservative", but meaning it in an Upper Case sense - and I think that is dangerous.

I suspect that kind of thing actually encourages people who aren't "Conservative" to think that their political adversaries are all intolerant. And worse still it encourages some people who are Conservatives to think that it's all right being intolerant of your adversaries. So both ways it encourages an attitude of intolerance.

...and the opposite of "Liberal" is "Conservative". Not so sure about that one. I'd say it only makes sense to talk of a political ideology as having an opposite, if there are only two political ideologies. It's a bit like saying the opposite of an American is a European. I mean there are other pieces on the board, such as Radical, Libertarian, Authoritarian...
