If you genuinely believe that then you're just plain wrong. Let's see on Saturday how many times people sing 'Chelsea rent boys'. The premiership is a GLOBAL brand. We've been enlightened and we should all back a moral crusade into the parts of the world where being gay is punishable by law. Just because someone belongs to a 'highly vocal minority' doesn't mean their rights to live in a safe community are null and void.
That stat you've posted is probably incorrect because there's always a 'dark figure' when discussing a taboo subject (hence the no answer brigade). If it's 5% that's 1 in 20 people in the country who would describe themselves as being LGBT. In Manchester I'd argue it will be even higher than the national average (same with places like Brighton). So In a community like ours these campaigns are definitely necessary.
You might not be bothered, but other people will be. This campaign has got people talking - it's shown that the majority of City fans are enlightened and will hopefully encourage lots of younger men and women will feel more comfortable living the way they were born.
