You're forgetting the self-loathing whites, stoned hippies/crust punks, hipsters, most arty twats etc.
I'd be alright with them if they didn't try so hard to force-feed their views upon others, but sadly they do. Fingers jammed up the media's arsehole, for example.
Other things you usually notice with liberals:
Changing songs/books/being revisionist eejits in order to "not offend" others, but the extreme PCness offends anyway which in turn becomes a type of unPCness.
Trying to have pseudo-socialist views when their families are well-off and get daddy's check every week.
Try to look as pompous and ridiculous as possible, especially hipsters.
Seek equality and love when they're the very definition of inequality and hate, just like everyone else.
Extreme pretentiousness, especially if they're art/philosophy/politics students.
Defending people when in reality they probably caused the problems themselves, eg. Muslims.
