@nwkoslvtz its okay, that's absolutely not dramatic at all, it is absolutely reasonable to freak out over that, /especially/ if you have previous trauma regarding it. it just set off the fight or flight/panic response in your brain because its similar to something else thats happened!
if you PURPOSEFULLY misgender a trans person simply because you do not like them, even if you are gay, lesbian, bi, queer etc,
you are still transphobic
