That's like saying the KKK or Black Panthers are part of US society so US boxing fans are racist i.e. it's a load of nonsense. It had nothing to do with the thread title. In actual fact, the UK is one of the least racist nations in the world.
The thread question was about boxing fans, not racism in the UK. Posting a load of videos of chavs on trains/buses which are completely unrelated to boxing is pointless. It's the equivalent of posting random racial attacks in the US and somehow relating it to boxing.
