I’m constantly baffled by the exclusion of bisexuals. I blame bad science, or rather bad scientists. Every year it seems there’s a new study on “what makes people gay”. Oddly, this is expected to be an on-off switch, and the researchers look in the genes, or the brain or the length of fingers for a sign that one set of people will be queer, now and for always, and another proving the rest will remain 100% straight. It takes a special kind of rigidity of outlook to construct a survey on finger length and decide beforehand there’s no middle ground.
