Football hooligans /Nf/Edl vs gangs

Yo have any of you lot on here experienced or no any stories of football hooligans , national front or Edl going at it with street gangs? Im from south, I always found it strange how Bermondsey and millwall was so racist despite Peckham literally being round the corner. From what I’ve heard the Bermondsey millwall lot would attack random Black civilians but didn’t want no problems with the Peckham lot.
