The government already intercedes in marriage beyond prohibiting gay marriage.
In most places, I can’t marry my 14 year old neighbor (I love her, it’s not my fault she’s younger than me and I don’t want to have to wait for her to be 18).
In most places, I can’t marry my sister (I love her, it’s not my fault we are related).
In most places I can’t have more than one wife (I love them both and can support them, why can’t I marry them both).
Well, WTF!! Who’s business is it who and how many people that I marry!
I suppose that all you gay marriage supporters were outraged that the government raided the ‘polygamist’ compound–you know, the one where all the women were happy being there?
You can’t have it both ways. Either EVERYTHING is ok when it comes to marriage or society, as a whole, can determine what we condone as the social norm.
