Thank you for the additional context, VMisaMarshmallow.
For science, academia, non-emergency healthcare provision, etc, I acknowledge many of those valid concerns. Kindness, respect, and actual science are important. (Although, I don't think that criminals who do terrible things are a reason for preventing law-abiding citizens from being their true genders. Most people don't lie about their gender in order to commit opportunistic crimes; most people aren't criminals - or, even just deliberately unkind.)
However, physical appearance doesn't always match gender stereotypes regardless of sex or gender. Should Harnaam Kaur not be offended if someone says she doesn't look female? Or, should Thomas Neuwirth not be offended if he's misgendered when not performing as his stage persona? To the best of my knowledge, both of those people have some physical traits that do not match gender stereotypes. Physical beauty/appearance is always subjective; I'm sorry but it is definitely offensive to tell someone they don't "look" sufficiently gendered.
