Livre d'Or

I agree with you that everybody is individual in their sexual preferences. I do have considerable sympathy with the argument that it should be a completely private thing which doesn't need a label and is only relevant to the people one is actually considering being sexually involved with.

Politically, though, there is some use in having labels so that you can pay attention to and do something about inequalities. Like, if people who are in love with someone of the same sex don't have the right to marry their partner, and risk getting rejected by their families, discriminated against at work etc, it's useful to be able to discuss "gay people" as a general category.

I think bisexual is a reasonably useful category, because bi people collectively have somewhat different experiences from people who are exclusively homosexual. Although I kind of mention it jokingly, I don't think sapiosexual is a particularly useful category, because there isn't really any common experience between people who are attracted to intelligent partners and repulsed by stupid potential partners. Some people are concerned that bisexual as a word is hurting non-binary people, whom I don't want to hurt. This is not an abstract hypothetical idea, this includes some of my friends. I basically agree with Serano that in fact it is not my fault for being bi, if some people are prejudiced against non-binary people. But I think it's a question worth considering, all the same.
