"Remedial audience training"? LOL!

Mrrzy, it seems to me that you're asking a couple of different questions here:

Is your lack of enjoyment of watching performers be drunk or rude "just a You thing"? Absolutely not. See the "Performers Excess Drinking at Gig" threads, for example. I'm sure there are threads about performer rudeness and its effect on audiences, too (if not, there should be!).

Is your lack of enjoyment of SEEING the sweaty people doing things that you wouldn't have known would produce those sounds "just a You thing"? ...Well, I've never actually met catspaw, so I can only imagine the unpleasant visuals that go along with the noises...*G*

But seriously, I'm sure you're not alone in your disappointment with some band performances, their appearance, their synthetic instrumentals (one of my pet peeves!), and so forth.
