I think the anti-racism campaign in football worked because it because unacceptable in other social circles before or around the same time. I still fell that this country is more inclined to be homophobic (even in jest) in everyday life, so a full scale campaign - whilst working to some degree - would not that the impact of the anti-racism one. Plus, the fact is that with the anti-racism campaign, your average Dave The Fan could see that he had black players in his team, and he cheered them on. There is no-one for Dave The Fan to link homosexuality too in football bar Justin Fashanu, no-one in his team. That is the reason it would fail. (IMHO, natch)
