The twitter account is bonkers. I read through all the posts, and bar one, possibly 2, saw no evidence of transphobia. I think they need to look up the meaning of it.
This is the problem - there is no commonly agreed meaning. Some would say it's transphobic to say you don't believe a man can be a woman, that research should be one into issues of medical ethics etc. But critical thinking, research, being able to state different beliefs and name reality are important and need to be retained.
TRAs are very keen that only they can define transphobia. And then it is used to mean anything that doesn't suit their agenda. So today it was leaflets pointing out biological women are at an unfair disadvantage in sport.
Mumsnet (and society) can't be run on not saying things TRAs define as transphobic, because that becomes a way of censoring anything women say that relates to the differences between biological males and biological females. Which is the BASIS of feminism, and of women's protections in society and law.
And that becomes effectively censorship of feminist thought and discussion of women's sex based rights.
Talk guidelines (and law and society) need to make sure that doesn't happen. If TRAs or gender ideologists write them it's pretty much guaranteed it will.
