Wtf is "misgendering"?! Genuinely have no clue what this might be and whatever it is was totally and utterly non-intentional.
To those who doubted - this is 100% genuine.
To those who thought I was being rude that night - I'd like to make the point that nothing I said was directed at the person. I was making genetic statements for the purpose of conversation, not carrying out a personal attack on one person.
If this stays up then I will post a screenshot of the text I received from the PO.
