I don't think the ruling they are debating fixes anything that either side thinks it does
How would you know?
Much of this "debate" has seen Starmer's past statements ridiculed for sport by the right wing media, those parasites bring nothing to the table, they're only interested in the heat, not the light. Unfortunately there's one statement Starmer made back in the day that has not been recycled to embarrass him, it's when he said "this is not a zero sum game".
What this ruling has done is to blow that statement apart, it was and is a zero sum game.
Before this ruling the gender warrior dogma was trans women and cisgender women were both oppressed by the same groups and for the same reason, because they are women, so they shouldn't be in conflict. This "biology" divide and rule was deliberately confected by their oppressors to keep them fighting each other, rather than fighting them, instead they should unite as women against the oppressor, the rich, straight, white, cisgender men.
This bollocks is central to the intersectionality wheel of privilege nonsense.
But women aren't buying it, they know it's bullshit. Women are more than their biology for sure, but, and this is where the ruling nailed it, they are never less than that, they are never not that. Nothing makes sense, certainly not the law, if this is not acknowledged.
Why?
Because women’s oppression is rooted in biology and so consequently the rights they've fought for are rooted there as well. Their biology unites them as a sex class, it's the one thing all women have in common regardless of social class, status, wealth, education, sexual orientation, politics and skin colour.
Put simply only women can have children and men are stronger and more prone to violence when it comes to getting what they want and only they can rape.
All women know this.
At a very basic level, if you were looking for an overarching oppressor of women you would have to say it's men, but that's true of men whether they're wearing a suit, a priest's robes, or a bit of lippy and a dress.
And women know that as well.
