They need to cling to the "passing TW" and "you can never tell" because they use it for the "therefore there is no point to single sex spaces" stuff. Although of course, they never argue for designated unisex spaces, which would be the actual logical conclusion of that. They still want designated single sex female spaces, so that men can use them. I don't know how their brains don't melt.
They also never suggest that we ditch all traffic controls simply because some people get away sometimes with running red lights or speeding. They certainly never suggest that getting away with it means they weren't doing it. It's only women's rights and safeguards that they think are pointless if they can't be perfectly kept at all times... and that, in yet more irony, is precisely why we need them.
I'm done with their lies, their gaslighting, their sexism, their absurdity, their fire and brimstone rhetoric about how we are more evil than Hitler, their foot stamping and pretence. I'm absolutely done. Even if we lost every court case, even if the entire world became a deranged totalitarian state that hangs everyone who says men aren't women and never reverts to sanity, it wouldn't change reality. Men aren't women. It's that simple. They're just not.
