What is it with some of you, I have made a perfectly inoffensive debatable point from the question that was put before us all, disagree with me by all means, but please stop the name calling i.e. bigotry, ignorant, etc.

/// Around 6% of the British population are gay, according to an estimate by Stonewall, a gay-rights charity (though other surveys reckon the number is lower). But little definitive statistical evidence exists on how they vote, says Joe Twyman, of YouGov, a pollster. Generally, he says, they tend to be slightly less fond of the Conservatives than is the population as a whole, and slightly more likely to support Labour or the bedraggled Liberal Democrats. ///
That takes care of the political leanings, as for the high proportion of LGBT people in the ats, perhaps that is down to the fact that more people are willing to 'come out' than in other professions, for example one being in soccer.
In films for another example the days are over when such gay actors as Rock Hudson had to be portrayed as a masculine hero.
