am i the asshole?

I accidentally called my trans friend their dead name and now shes mad. she told me “youre gay you should inderstand how i feel” and was all emotional or whatever. like yeah ok im gay but that doesnt mean i have to go through a whole gender journey so i said “girl i aint no tranny” and reminded her i have almost no lgbt friends. now im blocked and being called a traitor to my community. like help all my friends are non performative guys and abgs, ask me about matcha and ill know all the spots.… like i dont even know how lesbian sex works so how am i going to understand a trans persons mind.
