Are you deliberately missing the point to justify your own ends? Get your head out of the sand.
Surely your life is not ALL banter is it? As the man says it is sometimes gets out of hand. One guy has already said that his wife finds some of it offensive. Fair enough?
As for 'naughty' language it's banned on PPRuNe. Not a bad thing when you see some of it either. I can eff and blind but not on here I don't!
