Actually it's a sign of strength when it's not unPC to make fun of a group. I wouldn't want that to change.

I actually personally witnessed a trainer on Sexual Harassment Avoidance say "You can't make fun of somebody because they are black, or a woman, but you can make fun of them if they are wearing a pocket protector because nerds are not a legally protected class".
Strangely, my reaction to this was not joy that we are not a historically oppressed protected class. It was more like "Why can't we teach people to treat all their colleagues with respect"?
Most people are quite capable of distinguishing between the professional stereotype and any individuals they may meet, though.
"And yet a group has to be powerful enough to enforce a taboo. Coprophiles, as of this writing, don't seem to be numerous or energetic enough to have had their interests promoted to a lifestyle."
It's not cool when people find it socially acceptable to say something venomous about a group of people.
