Stereotypes & the gay brain

OMG did I always (and sometimes not so secretly) want an Easy Bake Oven when I was younger. When my sister finally got one, I think I was the one who begged her to open it (and fast) and I was the one who quickly ran around the house and found the lightbulb for the heat source and screwed it in and set it up and applied all the decals just so and begged and begged her to let me show her how to make the brownies...and they turned out as good as something from a silver pouch cooked under a light bulb can taste. And I loved every minute of it.

A recent study has shown similarities between the gay male and straight female's brains. Some gay activitists are delighted by this biological finding that would seemingly further substantiate an "I didn't choose this" (technically, "sexual orientation is hardwired into our neural circuitry") response to opponents (or, to those who stubbornly or ignorantly still insist that "sexual preference" is a choice).

I'm more along the lines of thinking of Jane Czyselska, of the England's Guardian: Sexuality isn't that simple:

The idea that the male and female, gay or straight brain can be so easily categorised seems deeply problematic and appears to rest on outmoded and stereotypical notions of gender and sexuality. Where does this new research leave bisexuals? If gay men are hopeless navigators and straight men natural born Top Guns, are bisexual men only to be trusted with a map when they're in a relationship with a woman?

As I get to know more and more queer folk around Napa and nearby and different events and I've seen vatos and flamers and total queens and drag queens and have friends who are straight and gay and bi, I've come to exactly that conclusion. Sexuality isn't that simple. There are masculine gay guys and masculine women and it's not quite the same as one kind of gay or straight.

I might have loved my (okay, fine: my sister's) Easy Bake Oven, but there was much more to me (and to all of us) than typical gay stereotyping.

Does it help or hinder the queer movement with findings like 'gay men think like straight women'?
