Science is science, it's not something you either believe in or not. You said the scientific understanding of gender is baseless. That is your belief but it's validity is irrational.
"You said the scientific understanding of gender is baseless. "
i never did, but i'm pretty sure as we move on ironically we'll see that it is you that believes that
ok so let me guess gender is entirely a social construct and has no connection to biology whatsoever, even though 99% of people exhibit the typical characteristics?
here's a question, people get born with 6 fingers, toes, tails all kinds of shit like that and that's grounded in science since we understand that aberrations occur in reproduction
why aren't the people you are supporting in this asinine cause to destroy categories moving towards destroying the category of human as bipedal with 5 fingers and toes?
why is it that its only a problem when it comes to sexual identity? that should tell you something but i wouldn't be surprised if you haven't bothered asking yourself that question
if we say well intersex people exist so that shows that the concept of gender needs to be more fluid then to be consistent since the entire process is messy the category shouldn't exist at all
but of course any person still grounded in common sense understands that categories are GENERALISATIONS, no biologist has ever said that the categories are 100% going to apply to every organism, but we do the generalisation because we have to in order to make sense of things
