I think that’s an interesting idea. Also the fact that most people who think being gay is ‘wrong’ don’t know any gay people, or think they’re all the screaming queens type. I used to share a house with a gay guy who my dad had met - it really diluted my dad’s ‘born in 1950s Irish Catholic’ casual homophobia when he found out this guy who he really liked and respected was gay - and more importantly, that my dad hadn’t had a clue that he was.
The reason I’m mentioning my dad in relation to the OP is because he is not homophobic at all now, because of the love idea. The flatmate I mentioned had a civil partnership last year, and Belfast was the first place in the UK where these could be carried out. Naturally there were loads of protests from the religious right about this, but my dad said musingly, ‘You know, what’s the problem? It just means there’s more love in the world.’
I still think he would be uncomfortable with the stereotype of a very loud, very camp gay man bed-hopping every night, but he’s realised that gay partnerships are pretty much the same as straight ones in terms of love and commitment, and he would never want to deny anyone that.
