You're just ranting again. Give us some facts.
You know full well that you were referring to all the Nigel Farage voters in general as a rabble, otherwise you would have used a term like "some of them are". You've given the game away. Anybody can see what you think of football supporters. It's a sort of bigoted, classist thing when you put all footballers into the same category of drunk and disorderly yobs or is it just the football supporters that vote for Farage? I would expect that most football supporters are nice responsible people with valid opinions, but, of course, that can't be true for you because some of them vote for Nigel Farage!
There is something odd about soccer supporters, how they behave,and how the authorities respond. The same does not occur,as far as I can see in any other code. The violence outside the Oval , Twickenham, or Wimbledon,is order of magnitude less. Our Croke Park in Dublin,home of GAA ,a much more robust game than soccer, routinely hosts crowds as large as any major Soccer stadium,yet the supporters mingle together and josh each other. The police handle it just as simple crowd control.
I am rarely in London, but was present at Fulham road,getting an airport bus,at the end of some Chelsea match. The noise of the police sirens and their vans dashing up and down, should put anyone on edge.
