I do see that, which is why I haven’t said anyone is wrong to be offended by it. It’s literally in one of my comments - be offended by it if that works for you.
Would you say the same thing to a trans person who was offended about being referred to by their biological sex?
Because I can't help but see a real double standard here, in that when women (the old fashioned kind, with wombs, as Ricky Gervais would say) object to being called "cis", or "people with cervixes" or any of the many other expressions which trans activists are pushing to be used in common parlance instead of "women", we are told, "It's not offensive, it just means your gender identity aligns with your sex assigned at birth" or alternatively, "You can be offended by it if you like, that's up to you".
There is almost never any acknowledgement that the people about whom these terms are being used have the right to determine whether they are offensive or not, and certainly never any indication that the offenders will stop using these terms even after they have been told they are offensive.
By contrast, the whole of society is expected to essentially not use words which accurately describe people according to their biological sex, because it offends trans people.
How do you think it would go down if I said to a trans woman, "Calling you a man isn't offensive, it just means you're an adult human of the male biological sex, i.e. the opposite of a woman", or alternatively, "You can be offended by it if you like, that's up to you"?
Not well, I'm guessing.
Actually, I don't have to guess because I have said these things and they do not go down well.
Why is it that women should have to accept being described in a way which offends us and isn't even factually accurate, but that when trans people object to being described in a way which offends them but is in fact factually accurate, we are expected to modify our vocabulary and even limit the concepts we are allowed to discuss? (Because it appears there is no way of discussing the importance and immutability and binary nature of biological sex without offending trans people, whatever euphemisms you use.)
