Fucose mutarotase is queer

Studies like these always worry me. While many people see in them the opportunity to decisively demonstrate that homosexuality is not a choice, I see them as both (a) further entrenching an ideology according to which sexuality is a binary determinate property that accurately draws the line down the middle of two different 'kinds' of person, and (b) offering up hope to parents that might want to prevent gayness through genetic engineering, and doctors that would like to profit off of them.
