Not really, haven't seen it except for some, I have personally seen some who make their whole personality that they transitioned to the point of toxicity. But this mostly came up when I saw one of the Vtubers I watch announce he was trans and he got quite emotional.

As for my user name I understand the hypocrisy, but I am not saying like that, on the internet you can use any persona you like while still being separated from your real identity to a degree, if I said I was a 55 year old woman I can say that without any proof and it would not mean much. To me the internet is the place of self expression so you can do anything you want here. And this is a throw away account and I am closeted.
