What they get up to is not their business when it is done in public.
I couldn't give a monkey's who George Michael has sex with in private - I don't care if he has sex with 10 men, their grandmothers and their grandmothers cats at the same time - he can do what the hell he likes as far as I'm concerned.
But, if I was walking my dog on Hampstead Heath and came across a couple of blokes bumming each other, I would be offended and disgusted - that is my right.
I know it is 'right-on' to smile indulgently at theses practices but, and I'll brook no argument on this, turning Hampstead Heath into a no go zone after dark so that the George Michael's of the world can get their jollies is wrong.
