did people vote on this single issue, no. Was it part of a perception of her as out of touch, dangerously liberal etc, yes.
This is where I was in the UK elections. Labour had my vote and lost it. Different perspectives on gender with respectful and open dialogue with gender critical people (including those in the Labour part) I could have lived with, not least because I know the more the topic is properly debated and interrogated, the weaker the Genderist position becomes.
(And also because I think the possibilities and perseptives or gender non conforming people ultimately support Feminism and general human happiness, and I don't want to silence or ignore those perspectives and voices. It's the replacement of sex with gender, and the undefinition of sex-based rights, experiences, language and history that I reject).
It was the witchhunt, the refusal to see and understand the other perspect, the casting any disagreement as hate and bigotry, the celebration of cancelling, that lost them my vote.
Because if they will do this with gender, if they can look at the history of women (in the original sex-based meaning) and say "no, that word, and the history and rights that go with it, was a misunderstanding. All this never really belonged to female people at all; being a woman, and all that goes with it, is nothing to do with your bodies, it's just because you think like a woman and it always has been; your voices and expereinces, the facts of history and science, are irrelevant in this matter", what else will they do it about? What other facts, who else's rights, and right to tell their own story and activate for their own needs, would be next? Who else will be, indeed who else has already been, thrown out because their truth doesn't fit the narrative?
