"There was nothing wrong in my post, at all"
yes there was ... if you refer to an underclass - a term used by Edwardian middle class surveyors of the slums - and suggest that the Welfare State has produced these prats, you are very wrong. Idiots existed all through history. What you have here is a group mentality with power but no aim but mindless showing off.
I remember the actions of a group of rich University ex-Etonians who trashed restaurants. They were not under class or wefare-owt: one is PM and another Chancellor of the Exchequer.
It's endemic once you remove responsibility and care for other humans. That's why these villains deserve punishment.
Your post did not show anything beyond a Mail response: ie a political point for the far Right.
