Flounder strikes me as someone with empathy who's tying themselves up in knots to be kind and do the right thing, rather than a hardline TRA who couldn't give a fuck about anyone other than themselves - and indeed would get off at the thought of doing women down.
I think if someone has their identity tied up in being kind/empathetic/virtuous/lefty etc, this is quite a hard topic to grapple with - you have to cope with the cognitive dissonance of feeling at odds with your own tribe when you wake up and smell the coffee. It's easy to go along with the prevailing narrative and feel all pleased with yourself for being 'progressive' as long as you don't engage too closely with the nuts and bolts of it all (pardon the pun!).
It's really not comfortable to engage in a meaningful way with the issues raised on this thread if you're thinking all it's about is lovely, gentle trans women being unfairly kept out of the women's spaces they feel they belong in by mean, shouty, unfair older women. Being brought face to face with the real life risks and disadvantages being suffered by women and girls as a result of this issue is tough to swallow. It requires courage to face these issues square on and consider them thoughtfully and honestly if you're coming from a 'progressive' tribal mindset. I know, I'm a left-leaning softy!
I have hope that Flounder will engage thoughtfully and courageously, and not bat away anything uncomfortable knee-jerk style.
The virtue signaller said there was no science to prove that periods made you a woman
This, on the other hand, is nothing but arrant bullshit! I have no time for fools like this, trying to make mugs of us all. Though I suspect some of them are trolls, they're taking it beyond what even Chris Morris would try and get away with.
