It's
already more socially acceptable, just as homosexuality, and then being openly gay became acceptable. Where have you been the last couple of decades? Younger generations don't have the old, rigid and exclusionary views of their grandparents. They have friends/teachers/neighbors -- maybe parents -- who are gay, and know it's not an "illness" or something to be "fixed".
Equating gays marrying to goats marrying is no better than Santorum's man-on-dog comparison: demeaning, derogatory, and de-humanizing.
Government got involved when practically everyone was married, and the 'social value' of marriage was recognized in contract and property laws. You do know that still exists today, right? Especially when children are involved, and military spouses. It's not a matter of losing a primary bread winner (although the economic advantages are real) but equal legal status for couples as
their most important family member. Not their parent or sibling or 'domestic partner'...but their spouse.
Important non-governmental agencies give legal priority status to spouses, like hospitals looking for next-of-kin for life and death decisions. Same sex spouses should have legal marriage
parity. Imagine the Terry Schiavo case, but this time the parents are fighting her wife, and the marriage isn't legally recognized in the state.
I'd agree that married couples shouldn't have tax deductions just for being married. But it'd also be stupid to have a stay-home parent/retired/non-working spouse file as an individual, without claiming joint family or household income. All that just means our tax code is fubar and needs reforming, not that same sex marriage shouldn't be considered a secular civil right.
Religious groups can marry, or deny to marry, whomever they want, based on their doctrine. But those couples still have to apply/file in a courthouse for a marriage license, and have it recorded, to be recognized as legally married. Would you get rid of that, too?
