Struggling to see how that is racist in any way, shape, or form?
If this incident did happen, it does seem a bit strange, then the idiots need to be banned from football, I just can't help feeling this is just not true though.
Charlton away in August 2003 Jihai Sun scored the third from a narrow angle in the second half and we knew we had won, and it seemed like the majority of the possibly 2.5k away fans sung "sun jihai, he's a chinky not a thai" for a while.
If the same thing was done on the train to a Thai boy, including banging on a door it would be overtly racist, but fans think it is okay as it was accepted at games with banging the back of the stand. Singling a player out like Park or a passenger on a train isn't much different, yet some people can't see the difference and think anything is acceptable if they are in a crowd or in a majority.
