It’s up to interpretation, and I’m not sure how OP intended it, but “Stop using binary genders” doesn’t have to mean “don’t be a man or woman”. Once you add more genders, the system is no longer binary. If we assume that man = 0 and woman = 1, we can use the infinity of numbers between, as well as 0 and 1 themselves. Basically, if gender is a spectrum, there are no binary genders.
