Do you not worry about the issue, but still have a world that conforms to traditional gender roles (barmaids are chicks, barkeeps are men; noble lords fight and hunt, ladies do needlework; kings are always male, that type of thing)?
This is about as far as we go, when gender issues are brought up at all. We don't really worry about racism either; in fact, if anyone is likley to get riled up over someone's race, it'll probably be a PC. Nobody else really seems to care a great deal.
Though much of this may come from not really seeing much gain from including '-isms', for me at least, it's partly due to indecision regarding the severity of the '-ism'. Too minor (grumblings, minor comments in taverns, etc), and they won't even care to notice unless they feel like hassling whomever is treating them in a sexist/racist/etc manner. Much more than that (higher prices for half-orcs, people treating women as second class, etc), and they might just leave town, regardless of the peril about to fall upon it (assuming they don't get themselves in trouble over these situations).
Really notable '-isms' (militias/militaries who order women to stay out of combat, or the same groups who will likely leave a half-orc to die on the field, or societies that have strong, fixed roles for various groups, and who look down on those who try to go against the way of things) would likely lead to no characters on the receiving end of that treatment, opportunity to 'fight the injustice (or whatever)' or not, unless they were Neutral (or Evil) enough to really make a mess of things, and not necessarily for the better.
I wouldn't mind including racism or sexism in various parts of my campaigns, as it can present an interesting foe for PCs to fight - one that can't necessarily be beaten by skill rolls or the edge of a blade. Unfortunately, I don't think it would fly in my group, certainly not if taken to a notable degree.
