However, the traditional family structure these days is just as likely to be : single parent raising children, “blended” family with step children, parent and other blood relative (grandparent, uncle, etc) helping to raise children together, group child raising among a group of parents in a community. There doesn’t seem to be many problems recognising these as “family units”… and if that’s the case, then how is it going to further change or degrade the family structure if some of the people in those families are unrelated adults of the same sex (seeing as we already have related adults of the same sex eg mother and grandmother, and unrelated adults of the opposite sex eg mother and stepfather)? Widows have been allowed to remarry for milennia (providing for an adult unrelated by blood to parent children). I’d like to add that there are already many families raising children with same-sex parents. The only difference (lacking legal marriage for the parents) is that they get a lot of discrimination (which certainly doesn’t benefit the children) in various avenues. Marriage would address this, but not further change the definition of family.
Also with respects the point about gays possibly being less faithful in their relationships/less committed/whatever:
I have seen studies which actually refute this (no cite, I don’t have access to my uni library catalogue from this computer). However, if this were the case, a reason might be that heterosexual relationships recieve a lot more support and encouragement in our society. The implicit support from the government, families, tv advertising, in every social avenue, means that heterosexual relationships get a lot more support, both overt and covert, than same-sex/queer relationships do. This might be one reason why they are often percieved as being briefer, or less faithful, or in difficulty.
If this were the case, then “marriage” would actually help change this phenomenon. Wouldn’t the “family values” campaigners love that!
I’d like to add that, as a Radical Queer (think of us as being a little bit like the Deaf community as opposed to the hearing-impaired community) I personally reject the notion of marriage because it’s part of heterosexual culture, and I believe that queers can come up with their own, better, culturally appropriate ceremonies, family structures and methods of bonding. And yes, this can/may involve polygamy.
However, I recognise that not all LGBTI-identifying people are radical queers, and some of them would love to get married, and for that reason I believe that we should all work towards the day when that can happen, without losing sight of the unique queer culture we have developed over the years.
