Trans men are men, socially and legally. Describing them as women is simply incorrect.
Legally in what sense? I don't think they're being sent to men's prisons. I hope not anyway...
What does this mean?
At my workplace, one of my male colleagues calls himself "non-binary" and has "(they/them)" in his email signature. He looks like any other man to me.
As far as I can tell, it's more like a religious belief than any kind of distinct visual style.
And “visibly” as in I get funny looks and sometimes shouted abuse from passing cars. Is that enough for you?
My male colleague who self-describes with a "non-binary" identity has no obvious visual markers of this.
You are free to call yourself whatever made up gender you want in public and social life, but to the doctor treating you at the ER or to the forensic specialist examining your skeletal remains, you are still a biological woman according to science.
Science and medicine deals in absolute details, not in blankets covering everyone. When a doctor needs to treat you, they need to know your sex, weight and age, since the dose or treatment is highly specific on those variables, there's no such thing as an inclusive thing to cover everyone the same. Inclusivity here would get you killed.
> It harms no-one to say “pregnant people”
It also helps no-one now, and it also harmed no-one in the past to say "pregnant women", since no-one other than women can get pregnant. So why did it have to be changed other than for virtue signaling?
