Dirty -
I apologise profusely; I wholeheartedly respect annoying pedantry and indeed, irritating nitpicking!
My point was that whilst gay people can and do reproduce, it is a little silly to pretend that you don't need a sperm and an egg to do so. One comes from women, one comes from men. See, I can be an annoying pedant too!
Lenin - I have apologised if anything I said has offended you but to be honest I don't think that anything I've said is actually offensive. From what I've seen, no-one is trying to erase you or tell you that you shouldn't be gay. And no-one is saying that gay people can't have children - just that they can't do so without the missing ingredient from the opposite sex. Please argue that one if you will!
And I think this debate has been full of context and everyone falling over themselves to make sure their exact meaning has been understood. They're just giving their opinion and provided no-one is committing a crime / inciting hatred, everyone has the right to their opinion and to express it.
I'm going to leave this thread now but thanks for an interesting discussion everyone.
