I'd say it all depends on one thing, really. And that is culture, regardless of what world it's in.

If the role play takes place in a setting that is similar to or is what we call the Western world, women will be less respected. If you look at the history of the Western world, for the most part, females were restricted to knowing how clean, cook, grow vegetables, and how to please their husbands. So the likelihood of a female warrior in a medieval Europe role play will be lower, but not impossible, as some groups back then were known for the ferocity of their women. Outside of Western culture, however it was a whole different ball game for females.

In African kingdoms, women were allowed to become successful members in the business world and could deal great influence on trade. Many African/Native American people used to trace their lines through their mothers, not fathers. In ancient Nubia, queens were actually more important than the kings, which says a [I]lot[/I] about how women were treated outside of Western culture. Unfortunately, however, a lot of that has been changed and lost since the Western world forced it's way into people's lives.

So to put it shortly, it depends on how close the role play is to real life, and also the cultural settings. I hope I answered your question correctly.

As for female warriors in fantasy settings, by the way, I think a lot of it is blasphemy. I say this because half (And half is probably a big underestimate) of the female warriors in fantasy run into a tornado of blades with no armor but on their tits and ass, and somehow don't get their stomach sliced open. People have complained that it's hard to find a picture for their fantasy female characters because all they find are slutty drawings.

Realistically, if any chick tries going to war dressed like that, they are liable to get captured and raped in my book. There's my input on that.
