Actually, I think not.
For starters, alimony has been largely supplanted by "child" support, turned into alimony++. Unlike alimony, which is taxable income to the recipient, and deductible for the payer, "child" support remains taxable "income" for the payer, and is tax-free income for the recipient. And since the feministas managed to change the rules, so that instead of "child" support fees being based on actual costs involved in caring for the children, to a requirement to maintain the household at a certain standard of living (in Michigan, the poor schlub is required to maintain his ex's household at the standard to which the family aspired prior to the breakup), it's fat city for the recipients.
However, this is pretty much moot for homosexuals, because they are biologically incapable of reproduction, and in those rare cases where they manage to "pull it off" (to coin a phrase), the courts are apt to look as kindly upon them as they are now. In other words, when "Brent has Two Daddies", neither one of 'em will be The Evil Ex-Father, and thus, neither one of them will be beaten to a pulp by the vindictive court system.
Don't rely on any standards of law, common sense, or rational thought. We're through the looking glass. A whole new set of rules are in effect. They are a brutal affront to everything this country was built upon, but they've got the power, and they know it.
