at least rule
(lemmy.ca)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Since gender is a social construct, I'd say there are as many as we as a society construct. And if you grow up tomorrow and feel like you, as a part of this society doesn't see yourself in the ones we already constructed, you just construct a new one.
So I'd sa, how many genders there are is fluid. But absolutely AT LEAST 3.
