Intentionally misgendering someone is a dick move and generally people don’t want to hang around dicks. So first consequence is you’ll have other dicks for friends. Except, they’re dicks, so probably not gonna be very good friends each other.
I also hope you are self employed cuz intentionally misgendering people in the workplace is not a good look either. Better hope no one in earshot has a trans friend or family member.
No one’s saying you can’t be Your Best Inner Bigoted Self. We’re just saying the rest of us think it’s ugly and weak minded.
