Offence - rarely given, all too often taken.
This once great country of ours stood proud in that humour could be used in relation to many aspects of life and 'angry from Surbiton' was a figure of ridicule. Now, unfortunately, galvanised by the E&D police and litigation, 'angry from Surbiton' has found its voice and we are a poorer society for it.
As a one-legged, Welsh teacher, I know only too well how personal humour can be and I don't take offence - for myself or, as is figured here, on behalf of others. "Oh, how will an Irish builder feel" rages 'angry from Surbiton'. I'll tell you - if he is a genuine builder he won't give a stuff, because he too rants about the cowboys. If he is a builder but not Irish, he will laugh - having suffered the indignity of following up other 'builders' (often Irish) who regularly con the public, particularly the elderly.
Well done Mr Gubba, and don't let the politically correct 'angry from Surbiton' tell you any different.
