The fact that categories of sexual orientation are arbitrary…
Just to go back a few steps… Helen, what you said here ISN’T a fact. It’s a complete untruth, in fact.
There is nothing arbitrary about classifying sexual orientation on the basis of which sex you’re attracted to, any more than there’s anything arbitrary about classifying humans in terms of their sex/reproductive capacity.
There are real and immutable differences between the sexes. And for most people, their sexual orientation is equally real and immutable and is based on those real and immutable differences between the sexes.
Trying to claim otherwise, as you are doing, is what’s grossly offensive and homophobic: suggesting that only being attracted to people of one sex is as arbitrary as a preference for one hair colour is just ludicrous.
You are denying the reality of the world we live in. It matters when you deny the real difference between the sexes because of the huge power imbalance between the sexes, both in terms of physiology and in terms of the social power that has accrued to men over millennia of patriarchy. Which we cannot try to combat if we don’t recognise it to start with.
It matters when you deny the reality of sexual orientation based on sex because that’s what men and women have been discriminated against and persecuted for across cultures, across the centuries. The idea that people have historically been persecuted for being “same gender” attracted is just arrant nonsense.
I don’t see any attempt at a civilised, respectful discussion from you. Just lies, misogyny and homophobia.
