Andrew Sullivan can be a first-class squirrel- remember his fixation on Sarah Palin's kid?-

but he can do some thinking, and he's got real problems with the current gender dysphoria crap, including
You might imagine that, given this record, the queers would go out of their way to reassure us, to show how tight the safeguarding is, how they screen thoroughly to ensure that gay kids are not swept up in this. But they regard the very question of whether gay kids are at risk as out of bounds. Here’s a queer activist writer, Masha Gessen, saying that one thing “should be off limits” in this debate:
[In the NYT] there’s a [paraphrased] quote from Andrew Sullivan, the conservative gay journalist, who says, Well, maybe these people would’ve been gay—implying they’re really gay and not really transgender. That really clearly veers into the territory of saying ‘These people don’t exist. They’re not who they say they are.’ So that’s why it’s so painful.
No it doesn’t. It’s perfectly possible to believe that transgender people exist, but that children may not know who or what they are before they’ve even gone through puberty. I’ll defend the right of adults to define themselves as they wish and take irreversible medical measures as they please. I’d march in defense of those rights. I’m just saying something that we recognize in every other area: children are different. And children should not be self-diagnosing a medical condition.

In the same interview, Gessen also says that we can’t “distinguish [being homosexual] from being transgender” anymore. To which I have to ask: if we can’t tell the difference among adults, how on earth can we with prepubescent children? And if we can’t, and the treatment is irreversible, the safest option is to let them be until they’re adult enough to decide.

Don't agree with him on all points, but he's damn well right on some.
