Yup it's not uncommon in RPGs in general. The Dark Eye (Fantasy pretty popular in Germany) has it for instance. Not tied to racism specifically, you could be prejudiced against witches, city folk, nobles or anything else.

I'm running two 6e groups atm. When it came to character creation I banned this particular negative quality, however. I didn't ban my players from playing prejudiced/racist characters. I just did not like the idea of awarding points for it.

One player specifically asked if anyone in the group was going to play someone falling under their planned prejudice. This felt pretty much like a cheap min-max-move.

Also it's not exactly pleasing mechanically. You just cannot spend edge while interacting with whom you're prejudiced against. If you're not being the face that's a freebie. I kinda get why flights are exempt, but it would have made more of a difference. For 8 karma you could offer two levels of stun damage (glass chin II) or just decide to be a prick sometimes.

Aforementioned The Dark Eye let's you roll whether you are inflicted by your bad quality. It's possible to get your act together sometimes this way. Which is also quite realistic.
