I’m a bit of a comedy geek. I’d hate that kind of thing
That’s really unusual these days. Who were the comedians? What was the event?
Feedback to the promoter isn’t a bad thing.
Feedback to the comedian by groaning or not applauding, or walking out is OK. Heckles, except as you leave, are taking a knife to a gunfight.
Bottom line is, not all comedians are for everyone. you do not have a right to not be offended, but you do have a right not to be sold tickets to rubbish, and not to hear stuff which totally crosses hate speech boundaries.
If you do feel the show has been missold or is bad, walk out.
Staying for a show you hate, is a bit like sending back a steak which has been overcooked when there is only one mouthful left.
