I'd like to point out that there is solid science that suggests there are, on average, physiological differences between gay and straight men (possibly women too, but I'm less versed in this research). A great starting point is here: https://en.wikipedia.org/wiki/Digit_ratio https://en.wikipedia.org/wiki/Digit_ratio. Another example trait is the number of ridges on your thumb, for example. I'm not sure why people are so hostile to the idea that one of these traits might be in facial structure. I don't really see what the risk is.
