In your analogy, the only discrimination is against asians, unless you mean to imply that there are subsidies for drinking (in which case, I'd favor ending both subsidies and anti-asian laws). In the circumstance under discussion, there is discrimination against both gay couples and single people, and I favor eliminating all discrimination rather than moving a small group from the unfavorable to the favorable group.
Suppose I reversed things. I want to allow single people to stop subsidizing married straight couples, but still require gays couples to pay subsidies. Would you favor that? Somehow, I doubt it.

He's implying that non-drinkers are being financially discriminated against in a way analogous to single people regarding marriage financial benefits. Regardless if it's subsidies for drinking, as you mentioned, or otherwise the non-drinkers are being burdened.
What it comes down to is which is worse: A specific group being denied a right or a burden which that particular right imposes on the population that does not participate in it. Where you're running into trouble, in my opinion of course, is conflating these two issues together. Gay marriage and your problems with the financial aspects of marriage aren't an either/or thing, they're a completely different battle. Based on your comments I believe that the subsidy issue aside you really have no problems with gay marriage itself. So be happy that some people got more rights and gear yourself up for the separate subsidies battle.
Regardless, thanks for taking the time to single-handedly take up an unpopular opinion here.
