Politics will scare people away unless at a political event. Guess it depends on whether or not it's a deal breaker or not. I don't want to date someone who is asleep or pretend I'm something I'm not so it they are sheep then it's better to find out early than waste my time. I think libertarian girls love liberty so they are not going to be attracted to someone who tries to control them. I am attracted to guys that can make me laugh but that's not a libertarian thing.
Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves. - Matthew 10:16
