I genuinely wish I shared your confidence.
However, having seen not only these sorts of arguments made in court but also read the first instance judgment in Maya Forstater's case I am very nervous about leaving this kind of nonsense sitting there unchallenged.
Gems from that judgment include referring to Maya's "belief" in the fact that sex in humans is immutable as "absolutist" and when considering whether her views met the test of cogency and coherence states,
"Her belief is that a man is a person who, if everything is working, can produce sperm and a woman a person who, if everything is working, can produce eggs. This does not sit easily with her view that even if everything is not, in her words, “working”, and may never have done so, the person can still only be male or female. The Claimant largely ignores intersex conditions and the fact that biological opinion is increasingly moving away from a absolutist approach [...] On balance, I do not consider that the Claimant’s belief fails the test of being “attain a certain level of cogency, seriousness, cohesion and importance”; even though there is significant scientific evidence that it is wrong." (Truncated so as not to bore but all the bits in between are astonishing too).
That was the level of understanding in the Employment Tribunal of this land just a few short years ago, apparently. The judge who wrote that now sits on the Employment Appeal Tribunal and in the Crown Court.
So I take your point, but I struggle!
