You aren't disagreeing with me. You're disagreeing with scientific fact.
Everything I've just said is as true as saying the earth isn't flat. If your view had any scientific merit, it'd then be a debate and I wouldn't be able to just say "no". But you are saying absolutes like 'trans women are women' and 'sex isn't scientifically binary' - they are objectively, provably false statements.
I understand fully where your view comes from - a position of not wanting to hurt feelings, a position where societal reality is of paramount importance and 'technicalities' shouldn't get in the way of it.
But what you don't understand is the consequence of that. The Equality Act 2010, for instance, sees the concept of sex underpinning women's rights. If you dilute what 'sex' means, you utterly destroy the foundations of that. It's suddenly a castle built on sand.
All I can say is it's possible to acknowledge the scientific reality of biological sex, understand women's rights are underpinned by biological sex and want to progress trans rights. You aren't an automatic 'TERF' if you say trans women aren't women.
