If he wants to call himself a woman then that is his freedom to do so, but it is unreasonable to expect everyone else to do the same.
He, and the management of Twitter at the time, should have extended tolerance to those who don't share his belief that men can become women by self-decree.

There is nothing unreasonable about it. It's not hard and people change things all the time; they change names, phone numbers, job titles, etc., and other peope remember. It's just discriminatory.

Here is where the rules I proposed upthread apply: The only thing not to tolerate is intolerance. They only deserve tolerance if they tolerate others - it's a two-way street. (Rather than repeat the whole thing, see the comment upthread or click here: https://news.ycombinator.com/item?id=49442308 )
Why do you believe this is the same sort of thing as changing a name, phone number or job title?
There is a discrepancy too in that most people who think this idea should apply to sex don't extend it to other immutable characteristics like race. Rachel Levine was celebrated for calling himself a woman, Rachel Dolazel was pilloried for calling herself black.
He, and the management of Twitter at the time, should have extended tolerance to those who don't share his belief that men can become women by self-decree.
