I think the simplest way to remove racism -from football, at least- would be to ban black players. Basic maths plus commonsense and a dash of ethnic cleansing and Bob's your EDL uncle.
A ban would seem rather draconian...how about quotas like in the media, the Oscars, the Honours List, Police Force, Parliament, Boardrooms, Academia, Judiciary etc etc?
We could also insist on some white representation in the Olympic 100m final.
