Open Forum: Group Marriage - The Next Civil Rights Fight?

Opponents of same-sex marriage, argue that their biggest fear is the inevitability of polygamy and group marriage if gay marriage measures are enacted. They argue that allowing same-sex marriage is a slippery slope because once we sidetrack from the "traditional definition" of marriage as being the union between one man and one woman, that the institution of marriage will effectively have a loophole allowing polygamists to argue for their rights.

There is a growing movement among progressives and within the queer community to accept polyamory and group relationships, which are not to confused with polygamy. There are a number of families in the formation of a triad or quad, etc who all love one another and are in a committed relationship, and are indeed a family unit. Many of these polyamorous families also raise children, and it could be argued that those kids will grow up in a better environment, having access to multiple loving and nurturing parents.

Do you think the fight for recognition of plural marriage is the next civil rights battle? Will poly families naturally be next in line after we legalize same-sex marriages nationwide, and do they have a legitimate case?
