nayrt but as a nonbinary person i don't think anything you said was inappropriate! i think it's pretty rude to speculate about someone's gender irl, regardless of whether they're cis, trans, or nb. there's plenty of gnc cis people and trans people who are stealth/don't medically transition, so it's not like you can "tell" just by looking anyways. i don't mind as much with the pixel dragons, but i definitely understand why it makes some people uncomfortable.
