And a good answer to that is education and taught compassion, primarily in schools and by the Government. The answer shouldn't be that sex needs to be "eradicated" and removed from every single legal document/government form of identification like the activists website I posted on the previous page states. The lawyer is part of that movement as is the parent. That's coming very close to the kinds of "logical reform" those who believe evolution is a lie/the world is only 6000 years old (bones are fake!) or the earth is flat follow. Eradicate what is true about science/physics/biology because that is the answer to stopping it being taught/said/on display. That's not how you clear up misunderstandings and a lack of compassion, that is how you rile people up and get push back to your own message as people will always push back against things that do not align with evidence. It's why it's incredibly frustrating when movements with a good message arguably go too far and attempt to do unproductive things to spread their message.
Sex is the biological descriptor of your organs and what is inside your body (testes/uterus/ovaries/etc). Gender is the identification of what you assign to yourself. Hence gender dysphoria when sex and gender do not align. I know you know that, but I say to that why push to seemingly eradicate sex as if it's merely tied up in a social construct? It's not intellectually smart and it's only going to lead to even more confusion around gender/sex and people in the fields of biology especially feeling that they're being offensive to talk about what sex is. Then again, teaching evolution is STILL seen as offensive by some. We're not part of the animal kingdom! Yes, we are. Some might want to say that's an unrelated argument, but no, it's really not. When what is true biologically about us is observable across all other animals then it's relevant to the discourse.
