Gay people are put off football because it's still perceived to be hostile to gay people. It's not because it's macho. It's about how welcoming an environment it is.
I'd like to think that if a Jag or any other player publicly "came out" (ridiculous though the situation is, it IS still taboo in football and we need to break that taboo) publicly, that it would either be treated either with indifference or appreciation and understanding.
The point at which football can be said properly to have tackled this is the point at which it is thought unremarkable, and people feel genuinely indifferent across the sport.
