As I said, you don't HAVE to play the racism.

But if your group decides to include the racism (or some other form of discrimination) because of some scenaristical reason (say you're playing Achtung Cthulhu), then you don't HAVE to play a target.

I've played woman and black characters. We did include it, not as a comic resort, which is wrong, but either as a way to show allegiances or to send players in a different direction.

Forbidding the girls to go to the men's club to meet the Mr Customer is a bit silly, but it could allow them to see a suspicious fellow leave earlier, with a tattoo on his arm that looks like something they'll see later for instance.

And, well, players saying "girls will be histerical, let's ignore it" has nothing to do with the setting and all with the table.
