Once there was a confusion about what "liberal" really means, so some people decided to call themselves libertarians instead. Now there is a confusion about what "libertarian" really means.

Seems to me we have some kind of ideology-name treadmill here, which works like this:

• start a political movement
• become popular
• many people will use the name of your movement, even if they disagree with a few (or later: many) points
• at some moment those people will complain that you want the definition to include you, when you are obviously merely a fringe member of this movement
