Assuming the change is for the better of course. Each successive generation tends to believe they've invented sex and alcohol as well as knowing better than the one before. You can guarantee they whatever is on the edge of taboo or comedy now will be mainstream in a generation or so. We had feminism, LGB, then T and Q got in on it. There's only really bestiality and paedophilia (and our slightly hypocritical relationship with drugs) left I suppose, but give it another 30 years and we'll probably have comedians no platformed for nonce and sheep shagging jokes as they will be lifestyle choices. Sadly too late to support my claim that the cow just backed into me while I was having a pee :-(
