Fox and Narth versus the American Psychological Association for the lose!
Fox's is anecdotal -- "Look, this couple and this couple divorced! Never mind the thousands still married, many among whom have been together for years or even decades, without even having the benefits and protections affored married couples -- how many heterosexual couples can make a similar claim?" Odd the perspectives Fox chooses... And as to the NARTH, despite the myriad ways I could explain their statistics away even if they ARE accurate (might you not rush into an ill-conceived marriage if you thought this might be the ONLY WEEK IN YOUR LIFE you'd be permitted to do so?) but really, I'm not going to take seriously anything from a source whose open and stated purpose (and fiscal future) depends on making people think they shouldn't be gay. It would be like believing Pizza Hut if they claimed that people who eat pizza are 138% more likely to get promoted than people who don't.
At any rate, the "same-sex divorce" statistics have no bearing on queer people's capacity for parenting in general -- it isn't as if adoption agencies are going to grant children to couples (of any sex) who have been married a few months and are already on the rocks, nor is it probable that at any point in the brief, heated, tempestuous marriages questionably described by these articles they thought about getting a kid. Point being, I would hope that any adoption agency would evaluate any potential parents on the same strict standards for stability and security, among others, regardless of their orientation -- whatever the statistics, assuming adoption agencies can be bothered to scrutinize applicants more thoroughly than "Straight - okay; gay - no way," there's no reason same-sex parents should be blanketly barred from adoption.
What makes it unfair to a child not to have a mother and father? That's as baseless and unfounded as me saying it's unfair for a child not to have two mothers so ONLY lesbians should raise kids. The gender of two parents isn't important as long as they provide a loving, stable home (which not all will manage to do, of course, even given careful adoption agencies, any more than all heterosexuals will be able to do -- but the point is not proving that same-sex couples make IDEAL parents, just that they don't mess it up any more than straight couples... which I've yet to see evidence that they do.)
