I saw a performance of the Mikado a few years ago. It's definitely still being performed. It's also not one of Gilbert & Sullivan's finest, so if it falls out of the rotation, shrug.
As for the euphemism treadmill, or the ridiculous proliferation of personal pronouns, hey, if you don't care about or respect the people who are asking you to use those labels, don't use them.
That's what it comes down to--respect. Do you want to show others the respect of using their preferred words? Fine, go for it. There really isn't any law you're breaking if you don't show them that respect. It just means you don't want to show them that respect, for whatever reason you choose.
Respect is kind of like personal hygiene. If you want to be the smelly kid, go for it. People might not want to hang out with you though.
What's so funny about the great PC-hate is that people sit there and complain that others are spending too much time being PC. Now just imagine those same fools complaining about others spending too much time on their personal hygiene, pretty ridiculous eh?
What's even more funny is that some people think that politicians could be non-PC and do just fine...do smelly kids get picked first or last?
If you think about it, PCness is such a non-issue that it really brings to light how completely botched the US political climate is. If you spend the time to post a diatribe on PCness, you are supporting non-thoughtful/non-constructive discourse on important issues. You probably think bathtime is stupid and you probably think careful, respectful communication is just too much effort. Well, sorry to burst your bubble: politics are EVERYWHERE. Everything we do is awash with political forces and the more effort/thoughtfulness/care you put in to dealing with them, the more you will gain (at least the respect of your peers). On the flipside, the more you choose to ignore PC, respect, etc., the more you will find yourself an outsider and a pariah.
So the next time you read/hear someone expressing the ills of PC or the joys of nonPC, just imagine they're school-age kids complaining of the degradation of bathtime or waxing poetic about the virtues of smelliness.
