It is easy to dismiss the rioters as knuckle dragging oafs but there must be a reason why they feel the way they do.
Generally working class areas are deprived to start with, and the influx of migrants from other deprived/war-torn parts of the world does not improve the situation for the original inhabitants ...
It's easy because the rioters (those attacking random black and brown people, destroying property, looting and those just along for the ride, filming it on their phones)
are "knuckle dragging oafs". The vast majority are racists but there are also those who welcome any opportunity for violence and thieving.
If they weren't "knuckle dragging oafs" they might be inclined to ask why "generally working class are are deprived to start with" but most of them 'feel the way they do' because for 50 years or more they and their parents have been told that the reason is because of black and brown people.
In the early days the people that told them this were unashamed facists, racists and far right Nazis - Combat 18, the National Front, BNP etc. The humiliation of Nick Griffin on Question Time made them realise that they had to change strategy if they ever wanted to gain real power. So over the years they have become more 'respectable', cloaking their aims behind mainstream political issues and increasingly supported by people motivated by opportunities that a right wing, authoritarian government would bring for their personal gain.
The rioters are simply the foot soldiers for those that want to achieve this, 'thick as mince' cannon fodder that can mobilised to destroy democracy and their own lives simply by someone pointing at somebody who looks different to them. It's not a new tactic, it's was used by the same sort of people 90 odd years ago and for hundreds of years before that. Unfortunately there are still too many people too stupid to learn the lessons of history and to the realise that yet again they are being played.
