How do you deny someone's existence? Is it a ghost thing?
I have been wondering about this too. What
do they mean, 'deny my existence'?
Is this it? -- If I think I have changed from being a man to being a woman, then I may think that what exists now, as me, is a woman. So if you point out that, no, I am a man, I may interpret what you say as you denying that I exist.
-- Of course this is a mistake. There is indeed a denial of existence going on: that is, there is a claim that something does not actually exist. But what? What is it that is being claimed does not exist? In fact, this is the very man-who-has-changed-to-a-woman that I think myself to be.
Yes, you deny the existence of that man-who-has-changed-to-a-woman. And of course you are right to do so: there just is no such thing as a human changing sex, so it is actually impossible for such a thing to exist.
So, yes, indeed you deny my existence in a sense in the sense that you deny I am ( sc. I exist as) something it is impossible to be. That is a very special we may say etiolated sense, however. Of course you can deny my existence in this sense are forced willy-nilly to do so by common-sense rules of rationality, indeed -- while still accepting (and, we hope, duly respecting) my existence as a person with all that entails ethically, morally and legally.
[tldr: Whether I am trans or not, I can have no justifiable complaints about you denying my existence as something I am not, and a fortiori as something I could not be. ]
