Yet another religious cult raided

[Quark]

Gay marriage, whether you like it or not, is based on equality just like a marriage between 2 adult heterosexuals.
Polygamists marriages are absolutely not based on equality, they are just ' a nice' bonus for those who invent a new religion or an extra stimulus for men to join that religion.
Same goes for forced marriages that are still common in countries like the middle east and India.

I think you're having trouble with separating the abstract of polygamy versus the only type of polygamy (polygyny, to be specific, you never really hear about polyandry) you'll ever see on the news - cases of its abuse. These are forced marriages, mostly to wives under the age of 18.

If three consenting adults, of any combination of sex and orientation, want to enter a polygamist relationship I don't really have a problem with it, though most of society currently does.

That's not what we're dealing with, here.
