Interesting point. Not sure I agree with you though.
Imagine a young man who, in a state of alcoholic and peer-induced stupidity, goes out and gets himself a tattoo. Your lowering of the bar means that when he grows up and qualifies as a doctor he will still be able to get a decent job and be accepted in polite society. I think what I’m saying is that I don’t see why tattoos need to be judged. They used to be, but now we’ve got better things to think about.
There was a time, and there are still places, where long hair marks you out as a drug-taking layabout hippy and/or artistic type. Today it just means that you have long hair, and you don’t have to worry about being judged. I’m all in favour of this kind of liberalism.
If you’re talking about aggressive and confrontational lyrics to music originating in gangland being played in restaurants, then I’m right behind you. You might like this little article by Clive James too.
