You don’t have to accept being called anything. Doesn’t have much use outside the Internet anyway.
You don’t say “That trans person over there” or “That cis chick over there” or “That gay dude over there.” You say their names. (Or “that person” if you don’t.)
Because no one is really going to care about my sexual orientation in a formal setting or when they come across me or another random person at the grocery store.
You can call me a leaf for all I care. We most likely won’t be seeing each other the next day anyway.
