Second, create the image of a liberal, intellectual, sharp-witted "bad boy". Defend ridiculously indefensible positions, make inappropriate sexual suggestions which clearly aren't serious, every once in a while unexpectedly turn serious... basically, be entertaining, mysterious and funny.

When you're with girls who are passionate about politics and such, changing the subject away to "simple" humor doesn't work. Use political humor instead. Don't avoid problematic issues, but instead embrace them as an opportunity to show off your wit.

Essentially, try and be a bit like an Oscar Wilde character.
