If a person with XY chromosomes (i.e., a MAN) somehow manages to change them to XX chromosomes (= female), then I would be willing to acknowledge that they have succeeded in changing sex.
Not otherwise.

Yes until the technology emerges to change the DNA in every cell in your body, “sex change” is nothing more than a costume. Surgery no more changes your sex than putting on a rubber mask makes you an alien.
That’s fine if you really want to play pretend. But, don’t expect to be taken seriously by anyone other than the lunatic left.
