Kate Osbourne is a lesbian and a TRA. Yesterday, following the Supreme Court ruling, she published this article in LabourList, a Labour newsletter.

In it she says 'In this regard the court has said in almost all instances sex in the law refers to biological sex. This ignores the fact that biological sex as we see it is not just one biological thing,' a statement she fails to clarify.
This has been pounced on by people anxious to deny biology, who are talking about sex at a molecular and hormonal level, arguing that some women have higher testosterone levels than some men etc. And bringing the DSD card back into play.
Just flagging this up. Osbourne is likely to have been briefed by Stonewall or other interested players. I'm guessing it's one front that the TRAs will try to fight back on.
If anyone's in Kate Osbourne's constituency it would be really helpful if you could go along to a surgery and ask her to clarify what she means when she said 'biological sex as we see it is not just one biological thing.'
