As I've tried, perhaps unsuccessfully, to point out, this isn't the same as arguing that permission to marry should be contingent upon procreative capacity. I can see how it might come across that way, from a starting perspective of weighing one vast change to the status quo vs. another such vast change, and I think I've failed adequately to clarify that I'm approaching the question instead from a perspective of weighing one vast change to the status quo vs. no such vast change. It's a different question.
You're also characterizing this as a "vast" change. What is the vast change here? From a logistical perspective, it doesn't exist: you pass a law allowing same-sex couples to do the exact same thing that opposite-sex couples can...and now they can go do so using exactly the same procedures as opposite-sex couples could before, and obtain thereby exactly the same benefits (tax advantages of joint filing status, visitation rights, and a host of other small preferential treatments given to married couples).
Speaking of those benefits: while they exist, it is categorically impossible to uphold equality of rights and opportunities while opposing same-sex marriage. The only to reconcile these two positions is to either a) pick one or b) redefine marriage such that it confers no civil benefits (which would indeed be a vast change).

That marriage should now be an institution open to homosexual couples as well as to heterosexual. Taken in isolation, it doesn't seem like a big deal to me, either. But nothing in society exists in isolation, and quite aside from the historical novelty of it, many millions of people regard this particular change as a very big, and very undesirable, deal indeed.
The impression I have is that those with whom I've argued the point here today see no reason to doubt that they know better than those many millions who share this opinion - so much better, in fact, that there's no point taking very seriously any argument, opinion, or belief, other than that which they themselves advance, espouse, or profess - or at least already agree with on all substantial points.
I was that confident once, too. Sometimes I miss it. But nothing is ever simple, and pretending otherwise can make fools of us all.
And do you really want to equate homosexuality and infertility, which for all intents and purposes is a medical disorder? Is that where you want this conversation to go? It's not where I want this conversation to go. My sexuality is not a medical disorder.
As I've argued at length in this thread and the comments I've linked therein, I don't think it's reasonable to consider that standard met here.
