Whether or not they contribute anything to the gay civil rights movement, or any other cause, should be their decision.
That sentence really jumped out at me, too. This claim that they "choose to hide and deceive -- and to protect their incomes and images -- at the expense of contributing important weight and star power to the gay civil rights movement" is pretty telling. I guess it's one thing to oppose a military draft, but if you're gay, there's no avoiding the "gay civil rights movement" draft. And your "weight and star power" is the property of "the movement." Gee, if the whole idea is "tolerating" other people's choices, why can't they tolerate the decisions of others to remain private about their personal lives? That's a rhetorical question, by the way.
I knew I wanted to post a comment to this thread, but you already have said exactly what I wanted to say. Exactly.
