Acow, you stole my line. I've been dubbing the argument from tradition the Tevye argument for years now.

What can homosexual marriage claim to make it co-equal to heterosexual marriage, and superior to polygamy, incest or beastiality?
The thing is is that supporters of gay marriage - particularly those who do not support ANY of the other three - is a combination of things. First, the denial of the necessary
inequality of same-sex and opposite-sex marriage. They, in fact, do not argue that one is superior to the other.
Second, there's a bit of the tradition thing in there: that a marriage is between two people, and particularly in contemporary society, that no person has more than one marriage in the legal sense at any given time (whether or not other senses should be considered, I set aside for the moment).
Third, particularly for the polyamorouy (N.B. - I use this instead of polygamy because it's actually a bit broader than polygamy), they might well have a utilitarian argument. They might point, for example, to current instiations of societies that allow plural marriage and the plight of women in those societies.

It can only be justified if one rejects those two given reasons, and in fact most any reason, and simply argues people should be allowed to do what they want - even if they are in the minority.
Not strictly any reason. If those two are the
only reasons to consider opposite-sex monogomy superior to same-sex monogomy, the argument is in a fair amount of trouble. Consider each in turn:
(1) Tradition
This assumes an implicit premise, that tradition ought to be maintained. But it doesn't seem to strictly follow from the fact that something has been done that it should be done that way. It might give us pause in how we go about bringing about change - for example, how quickly we seek institutional change - but it hardly follows from this that there should be
no change.
Interestingly enough, the tradition argument is also a double-edged sword in this case: there is, I think, a case to be made that the contemporary notion of romantic love as the basis of marriage is actually quite recent.
(2) Majority Support
Open to the quite-often made statement that a policy being popular doesn't make it right. I'll spare the tired slavery example, since that itself reflects a bias of popular
opposition to it in the present climate. Instead, let's use something more argumentative: the so-called Assault Weapons Ban. There are clever arguments for and against it.
At present, I've seen poll results that suggest a majority would actually have liked to renew it; and personally, I think that, when we look at the arguments and data, the most defensible position is
against the ban. It adds nothing to the counter-argument to say that it enjoys popular support on whether or not we
should renew the ban, particularly to one who disagrees with the position.
Or to add a second parellel: polls also show most people support keeping
Roe v Wade around. You've done legal work, if I recall correctly. What does this contribute to the following position -
the Roe v Wade decision was decided correctly and well-supported by precedent?

I believe it can only be justified on the basis of freedom.
In a sense, you're right. The argument that I favour is one based on Amendment XIV, Section 1 - the equal protection clause. By my understanding, the current jurisprudence on this is to the effect of the following:
The state may not create a de facto or de jure distinction between classes of citizens, unless there is either a valid public health or valid public saftey reason for doing so.There's a very real sense in which freedom - and it's acceptable limits - is the basis of the argument. All the gay marriage opponent who accepts the above as the underlying premise needs to show is two things:
(1) That opposite sex marriage not being permitted falls into the above principle
(2) That the other forms of marriage do not.
To be fair, multiple forms of polyarmorous marriage may well not meet the second criterion; but it hardly follows from this that incest and beastility would not. There are, of course, other principles that can be applied - particularly since, when we deal with these sorts of questions, we must in part deal with sexual ethics:
The Principle of Consent: a sexual act is morally permissible if all involved parties give informed consent.
The Principle of Non-Consent: a sexual act is morally impermissible if all involved parties do not give informed consent.
This would, effectively, rule out: rape, paedophillia, and beastiality at a minimum. Of course, there's always the argument that things like 18 are arbitrary. But even this has a reply:
The law, like so many other things, has to deal with a series of quick-and-dirty heuristics. They sometimes misfire. For example, we presume full maturity at 18, but that doesn't rule-out the outlying cases of the immature 20 year old and mature 15 year old. Because we aren't an All-Seeing Eye in the Pyramid, we lack the ability to pass a law based on anything other than the general case.
QUOTE
But legalizing only homosexual marriage but maintaining the ban on the rest is simply without any objective justification.
Some sketches of arguments that would make the justifications work:
Polyamoury: Creates a signifigant potential for fraud, and signifigant problems with the tax code (for instance, the possibility of multiple common-law marriages).
Incest: Genetic defects in offspring create a public health problem.
Beastiality: Human-Beast sex is unclean to the point of a public health problem; inability of animals to give informed consent.
I do conceed, however, that there may well be no good, solid, legal reasoning for a continued failure to recognise plural marriage - though it hardly also follows that incest and beastiality are truely comparable.
