I actually think it's irrelevant whether it's deliberate dishonesty or genuine but very disordered ideas about what being a "man" or a "woman" entails.
For me the fundamental point is that Freddie doesn't have the moral right to impose her beliefs onto everyone else.
And the second the law allows for the existence of biological "fathers" who are actually the biological mothers the law has accepted that "mother" and "father" have meanings based on personalities rather than biological sex.
And that changes the meanings of those words for every single one of us who is a biological parent.
If "mother" and "father" are types of personality, every mother and father in the world now has to either transition to the one they think suits them best or accept being seen as that personality in the eyes of the law.
It's abhorrent and twisted. No one should have the right to impose their own sexism on the rest of us like this.
