It was considered long ago as such? Well, now it is being considered again. We didn't say jack about it in 70s when polygamy was banned? Hey, I was born in 70s. I doubt I could say jack about anything.

I'm not against any form of marriage, even I don't care if Woody Allen married his step daughter. As I said before, if they are of age and consenting, why do I care? Good for them. And tough luck for anyone who wants to put their nose in others' business, or put his or her marriage in a scale and say, oooooh, no, our marriage is so much more marriagy than their marriage.
