I've mentioned this before - there's a CBBC gameshow in which contestants have to respond to three quick-fire statements with the words "true" or "false", using the opposite answer from the correct one. So e.g. "The sky is green", "deserts are dry", "Spain is in America."
It's surprisingly difficult to do quickly, with the pressure of a studio audience. The "cognitive load" of doing so is quite high. (Bit like word-matching games where you have the word "green", but in blue font, or the word "large" but in smaller font than the rest of the text, and you time respondent's responses to clicking the mismatched words/colour schemes/font sizes relative to pairs which match).
Now put rules around "misgendering" (i.e. correctly sexing) into a courtroom context - like, for instance, the trial of Maria MacLachlan's attacker, where the judge insisted Maria use the word "she", and when Maria couldn't do this, reduced her attacker's sentence as a result.
Now imagine this in a rape trial... Complainant: "Then he pressed his penis against me..." Defence lawyer and judge: "you have to refer to the defendent as 'she'." Complainant attempts to comply, turns into a stuttering, incoherent mess on the witness stand, bursts into tears as she tries to utter the phrase "her penis."
(This is not a stretch of the imagination. We have seen attempts to compel women to use pronouns in a court setting - Maria MacLachlan. We have seen trans-identifying rapists - Davina Ayrton, Lisa Hauxwell, Karen White, to name but three.)
Compelled use of the wrong pronouns is an assault on women's freedom of speech and ability to accurately describe the reality of the world around them. It's an act of political violence.
