Just realized I never responded. Apologies.
Well sure, but many straight marriages could be hedonistic in origin as well. You think the 60 year old moneybags marrying the 22 year old stripper is an example of soulmates finally reaching eachother?
I don't really separate gay people from straight people in too many ways, other than who they're attracted to. I don't see it as one group mimicking another either, by wanting to be married. I respect your view on what marriage is, but my personal view on marriage is very different. I believe the "sacredness" of marriage is decided by the two (or more) people in it. Let me ask you, are you married? If so, do you feel that allowing gays to marry will somehow take away from the importance of your marriage or make it any less special?
