This is the logical consequence of the Transwomen are Women mantra.
Both the Minister for Women and Equalities and the Shadow Minister for Women and Equalities are in agreement that transwomen are women, along with most of the other politicians who are paid to protect the rights of women.
If you base your reasoning on TWAW being a true statement, and are determined to have it written into law, then you cannot make exceptions for enormous hulking transwomen who used to be third rate sportsmen but have suddenly transmogrifying into Olympic level women athletes. The inconvenient fact of their biological advantage has to be fudged and denied, any questioning must silenced or dismissed as anti-trans hatred. The Emperors soft, smooth feminine girl penis might be dangling in front of their eyes, but they are not going to admit to seeing it there.
We already know that facts are transphobic. Women get banned from Twitter for sharing statistics about male violence rates, and how they remain unchanged after males transition to transwomen. Though when a transwomen tweets telling women to "suck my big lady cock" Twitter allows that message to stand, and the transwoman herself is rewarded with a job as Women's Officer for Telford Labour Party.
