People who believe that they are going to be excommunicated and shamed, or whatever other dark things may happen to them, are much less likely to enter open, loving relationships. And they are also much less likely to have the self-esteem that is required to be monogamous and loving. And in consequence, they are much less likely to create families.

There is also somehow the idea that this gay thing is all just about indulgence in carnal pleasure. When I was twenty and felt that nobody could know I was gay, I was having sex with strangers in public parks. I don't think it was evil exactly, but it wasn't so great either. There was nobody particularly benefiting from it, except, I suppose, to the extent that it gave some pleasure to me and perhaps whomever I was with.

I grew up feeling that to be gay was a tragedy. I didn't grow up thinking that it was morally wrong, but I grew up thinking that it would make me marginal, prevent me from having children, and quite possibly prevent me from having a meaningful long relationship. It seemed that this condition would leave me with a vastly reduced life.

Our needs are our greatest asset. It turns out I've learned to give all the things that I need.

I don't accept subtractive models of love, only additive ones. And I believe that in the same way we need species diversity to ensure that the planet can go on, so we need this diversity of affection and diversity of family in order to strengthen the ecosphere of kindness.

In these xenophobic times, when politicians are stoking everyone's anxiety about threats from abroad, I would argue that engaging with the rest of the world is not only a luxury, in the way that travel is, but actually a moral responsibility.

I'm a huge believer in science. But I don't think it explains everything.
