Well, I believe, when it comes to criticism, that it's not always what you say but how you say it that determines how offensive it is. And that's as much about your choice of words as it is your tone of voice. Criticism should not invoke things that are irrelevant to the point being made. For example, if a trans person cuts you off in traffic, the criticism is of bad or discourteous driving, not the gender of the driver. The gender of the driver is less relevant than the make of car. And there again, if someone driving a blue Volvo backs into your car and drives off without their registration details, you can say, "I am appealing to the driver of a blue Volvo to come forward," but that is no reason to hate people who drive blue Volvos.
What people forget is TERFs are the antithesis of assimilation. Take this for example. You were a student who arrived in Brisbane, Queensland, in 1979, to study at the University of Queensland. You could speak English, but you arrived from Malaysia, and were used to certain foods. You ended up sharing a house with two Australian students near campus, and one of them said, "Okay, this is how we cook, here, Mate," and threw a steak into a frying pan, and emptied a can of baked beans into a saucepan and fried the steak and boiled the baked beans and then threw the steak onto a plate and poured the baked beans over it, and you copied them, you are assimilating. By excluding transwomen from women's spaces, they are preventing transwomen from assimilating. What many ignore is, transwomen are NOT men who dress as women, they are people who were assigned male at birth on account of genitalia, but who, in their minds, do not identify with it. Transwomen want to be viewed as, well, women.
