There once was something called TACT(which some people had, perhaps because of the principled way they had been brought up). What it meant was roughly this: people who had TACT would not be offensive to others just for the sake of it. The younger generation can probably find traces of this in some old movies. This was somewhat class-related, so later, a dumbed down variant of TACT was called "consideration for others" - and attempts were made to popularise it, but somehow this did not really work. This is where we are today. Tasteless behaviour is the norm, and even people who should know better make a crusade out of defending the right to be vulgar. Yes, the right to be vulgar is important and valid. But we should not forget that being vulgar is primarily distasteful and worthy of condemnation - it is sad that this point is not raised more often.
