I'm not sure that what I was getting at has been understood. Never mind.
Ok since I derailed, I will get back on track.
There is some rivalry between Bromley, and Eastleigh. And between Bromley, and Maidstone United (Welling United do not matter, since it is unprofessional to kill feeble targets).
On a larger level, there is little love lost between Charlton, and Crystal Palace (Millwall are beyond the pale for both).
On an even larger level, there is little love lost between Scotland, and England (and I have to say I laughed out loud when I saw the Jock boys holding a banner at a Scotland v Argentina game with the logo "Thanks for 1986").
Those are examples of overt racism, yes, but they do not matter. What does matter is kicking the crap of out of somebody because of the team that he supports, just because he supports that team. And that is assault. And it ain't just the British Isles where it happens.
