saying gender is not a construct is a strong/radical statement in the context of theory
To be clear, I’m saying gender identity isn’t a social construct (gender roles definitely are). And that’s hardly a radical statement given that there is a genetic factor to being trans, as evidenced by e.g. twin studies like this one which found a much higher amount of cases where both twins are trans among identical twins (who have the same genetic code) than non-identical twins. Also, like I mentioned before, a lot of trans people feel considerable relief to their own gender dysphoria upon seeking hormone therapy and gender-affirming surgeries, which is quite hard to explain on a social basis.
