Politicians do politics. And it's seldom good politics to agreed too much with your opponents. Labour are doing this, and so is Badenoch. The government KB is a minister in, could introduce this legislation themselves if they wanted to, they've been in power long enough, and they haven't.
None of which is to say that I don't share the OP's bleak view of the future under Labour; they show no sign of freeing themselves from the pull of the genderist movement.
