Government should not be in the 'marriage' business. If two people want the legal status of being 'together', and want it through government, it should be a civil union. The same as marriage, without the church. The government should recognize 'marriage' as a civil union performed per a church. Thus be it done through a church or through a judge, the legal standing and rights should be the same.
And don't fall for the 'this party is against/for' gay marriage or anything else. Their actions speak louder than the hot air that emanates from them. And even the actions of those that (supposedly) support such things, show they really haven't done anything to move towards full equality on this issue (and many others).
