Gay men's brains respond like women's????

The NY Times reports that the brains of homosexual men and straight women respond similarly when exposed to male pheromones. Specifically, an area of sexual arousal (the hypothalamus) in women's and gay men's brains is activated by an odor derived from male sweat, while in straight men it activated odor-related areas and not the hypothalamus. It seems some chemicals can be treated as a "scent" in some cases (e.g. straight men) and a pheromone in others (e.g. gay men and women).

This sort of finding demonstrates what I've been saying for years: it doesn't matter if homosexuality is genetically or environmentally determined, or both, all that matters is whether there is a biological basis for homosexual arousal/behavior. Since this appears to be the case, everyone who thinks "gay" is a lifestyle choice for everyone just might have to help themselves to a piping hot mug of "shut the hell up".
