I remember during GamerGate there was one semi-prominent MTF (not Blaire White) and he was generally pretty chill, but I do remember him once getting upset because people were joking about women with facial hair and he got all assmad asking if he'd never be considered a real woman because of his stubble.
I wonder what became of him, I think he called himself Chloe but I can't remember his @.
Other than that the only other troon I've ever met personally was another MTF who was generally fine, apart from him bringing up being misgendered before he'd even been introduced to me, then later he slid into my DMs and was acting a bit too comfy with me, so I ignored him after that.
