Homosexuality is not paedophilia. Most child sex abuse is committed by men on girls.
Having said that, I find it difficult to believe that the two coaches at the centre of the current scandal did not also have consensual sex with adults and that those adults were unaware of the exploitation that was going on. There must also have been officials at both Crewe and Newcastle who at least had suspicions that abuse was taking place. Part of the reason for their not speaking out must be the lack of honesty within association football. Even rugby admits that it is no different from the rest of society, that there are gay men playing and officiating at the top level.
Even in the midst of another miserable playing season, Charlton Athletic FC maintains its Protecting Children Policy. Charlton was probably the first club in the English Football League to realise the need for a formal system of child protection, possibly in response to the news of Crewe Alexandra's trouble in 1998. It seems that not every club has yet caught up.
