Absolutely. The word gender has become synonymous with sex.
It makes talking about sex blurry.
When you have transactivists claiming that gender is something 'in their head', but, funnily enough, translates to their rights based on sex (about bodies, not heads), it's easy to see how it works for them, and against us.
It's only when you ask, outright, to a normal person what they think the difference is, that they start to think.
How does a woman think?
How does that manifest itself?
Give me a list.
I want list, please. I want the top five things that makes a man believe he is a woman.
It can't happen.
Even if you ask for just one thing.
Because the definition of sex is a description of reproductive function.
That's it.
But it's only when you put someone on the spot and say go on then, tell me, that they get it.
