There are no established, physically described ethnicities apart from Elves.
I approve of racism against the smelly Elves.
Whats everyone elses opinion?
I'm of the opinion that A. Stop if a friend is upset (which is common, some people genuinely have thin skin about a host of topics), B. Don't be offensive for offenses sake, C. Keep it detached from the real world.
I'd like to think the game is PG-13 when dealing with the public, but I expect you can go R with a smaller group that has made it clear that they are comfortable with it. The biggest part of 'playing with friends' is knowing which group of friends is willing to accept what.
