I requested to change my username due to gender stuff. But it was rejected ): . I thought that was a valid reason.

bump

did the st state why it was rejected?

Here is the email, and the rejected it. But I said it was due to gender reasons ):.

It’s dependent on a few factors. For example, of the valid reasons, the top accepted reason would probably be for safety, then gender dysphoria.
However, even if it’s a valid case, it is still rare.

i am confused why the rejected it

I changed my username. If you want to do the same, you must have one or more of the following wrong with your name.

Inappropriate (Swears, making fun of people)
Contains personal information (Last name, Email, phone number)
Causes gender dysphoria (If you are trans but your username has your deadname or pre-trans gender)

If you wish to change it, please contact them and state your problem. You just asked for it to be changed. I don't see an area where you stated why you wanted it changed.
