No, I don't see it. I see bigots attempting to justify their bigotry with irrelevancies. What's relevant is: "this person identifies as X". I'm not sure what you think gives you the power to say "oh, no, you can't identify as that, you can only identify as this".
It's their individual right, not yours.
You can't see the difference between a physical event and something that happens over time in the human mind?
If you can't see the difference you have no eyes.
Are you saying this Dutch guy did not over time in his mind decide he wants to identify as 49 years old? All the evidence suggests otherwise.
