You’ll tie yourself into complex ideological knots on this one. What do you do with someone who is Neutrois or Agender or Omnigender? Or someone who identifies as gender-queer? You’re only attracted to them on the days that their gender identity matches their sex? On days when their gender doesn’t match their sex, you find them repugnant?

Gender is a social construct — and an arbitrary one that is becoming increasingly meaningless. I don’t follow your example. If I am attracted to a female and she chooses to identify as male (by adopting male mannerisms and clothing) then I am less likely to find her attractive in a social setting— but take away the clothes and mannerisms and you’re left with biological attraction. Give that woman gender reassignment surgery and a penis and I am unlikely to find her attractive because she is biologically a male. The same is true with Ru Paul. was massively attracted to Courtney Act in the social setting of Ru Paul — but not at all attracted once you take the clothes away.

How someone chooses to express their gender is entirely up to them —but it’s a mutable characteristic and a social construct. It’s a combination of fashion and behaviour — all of which cannot be objectively measured in any meaningful capacity. Tell me what ‘female gender expression’ actually is — and give me an objective measurement of what that means in practice.
