Am I allowed to state that someone can't change their birthday?

Am I allowed to state that someone can't change their birthday, or is that also transphobic? Maybe it's fine if I say that it's my opinion that you can't but we don't want to state definitively. Like, I've been told that I can't deadname anymore, so I guess this is dead-birthday-ing?

Apperently, your birthday is the day you transition. Am I allowed to speak against people that say that?

I...don't actually get why this matters to you? Why is somebody's original birthdate relevant?

The Mod Ogre: Basically, yes, it is transphobic, because you are willfully ignoring the specific cultural context in which "birthday" is being used. It is little different than insisting that someone must always remain the name they were given at birth; you are insisting that only your definition of "birthday" may be used, rather than the definition of the community that is affected. In gaming/fantasy terms (and somewhat trivially, to avoid other political topics) it is akin to insisting that Raistlin cannot be a Wizard, because Wizards are Maiar spirits sent to Middle Earth, ignoring that "Wizard" is being used in different, and well-understood and established, context.
