So it turns out that people do now seem to think of marriage as some kind of odd, official seal on a loving relationship, IOW the meaning of the term "marriage" has shifted - in that sense obviously there's nothing wrong with gay marriage.
But if you think of marriage as a contract (hopefully between people in a loving relationship) for the purpose of procreation, and any state involvement having to do with giving a few special privileges to men and women who decide to settle down and procreate (settling down being necessary for the child-nurturing follow-on from procreation), then gay marriage is an absolutely absurd and bizarre concept.
Then you could say that gay couples can adopt children, but that bumps up against the missing biological mother/father (i.e. the missing member of the opposite sex to the couple, the role model for that gender not being present, as it would be with a hetero couple adopting). Plus also, there does seem statistically to be a fair bit of instability and nastiness in gay relationships.
It's a vexed question, and there are different ways of looking at the costs and benefits (for example I'd much rather have widespread adoption by gay couples than widespread abortion) - but in the fashion of the day, it was railroaded through by silencing the opposition as big meanies who want to spoil everyone's fun.
Culture has made marriage about the seal of a loving relationship to make it more acceptable that people can rescind the contract when they no longer love each other, since being trapped in a relationship you don't want for the sake of not being socially shunned is a trait typical of pre-modern societies where social ostracism is a practically a death sentence, while societies where individual rights matter put the desire of the individuals first and social disapproval is no longer codified as a law. See also how adultery is a matter of private morality and not of public disapproval to be punished legally these days.
However at its core marriage is still a contract, one that is about sharing money and goods purchased together, about inheriting from one another in case of death, about having visitation rights when your significant other is in a hospital or in jail, etc. The shift, from a legal point of view, has been from "contract between two families for the propagation of the families into the future through offspring" to "contract between two individuals in order to run a private enterprise based on common interests". Again this is part of the transition from communities to individuals as the core of legal rights.
Gay marriage, from a legal point of view, should be about recognizing the same individual contractual rights to all individuals, regardless of sex. The problem with "gay marriage", in a society where individual rights are the main legal principle, is a social one, not a legal one. Socially speaking gay relationships were legally forbidden due to religious values/social disapproval: once that's no longer recognized as a valid legal principle (the country is secular) arguments against gay marriage no longer carry any legal meaning.
Indeed the debate about "gay marriage" isn't about giving same-sex unions the same legal rights (inheritance, common ownership, visitation rights, social security, insurance, etc.) that opposite-sex unions enjoy (with the exception of adoptions). It's interesting to notice that "domestic partnerships" or "civil unions" are basically marriage in all but name (except, often, for adoption rights), and yet even most very religious people aren't too opposed to them, at least in countries with a legal tradition of having individual rights as the main legal principles.
So the big debate isn't about whether people in a same-sex unions can have social security or insurance rights, or inherit from one another, or have visitation rights, etc. Pretty much nobody in individual-centered societies is strongly opposed to that. The "gay marriage debate" centers around three points: the question of the name of the unions, adoption rights, and the matter of private businesses refusing to serve people due religious reasons.
Of these three points one is relatively trivial (if two contracts give you the same kinds of rights, does it really matter how you call them?), but a change in name, from "marriage" to "civil unions/partnerships" shows that many don't see it as such. The matter here is social, though, not legal.
So the main points where a debate can be had are adoption rights and refusal of service. In the case of adoption rights the problem is about the rights of the children and a cost/benefit analysis of living with two parents of the same sex vs. living likely without parents but under the warden of the state (interestingly, when the question is put in these terms, support for adoption of gay couples increases, probably because some people who don't see same-sex couple adoption in positive terms see it as a lesser evil compared to being an orphan). Also it's possible, as you argue, to suggest that abortions could decrease if more couples were allowed to adopt.
The question of refusal of service is a different matter. It's actually a matter of refusal of service in general which has only emerged due to the gay marriage debate, and it's not tied to a discussion of individual rights but of anti-discrimination laws (can private businesses refuse service to a particular group of people?). I think that putting it under the big umbrella of "gay marriage" muddles the waters.
