Do you agree that there's more than 2 genders?

Since this question is not about sex, I'm not going to get into that. But if you want to call a transwoman or transman a third gender, well, that's on WHO's guidelines and I haven't checked but I bet its in the grey area. Then there are people who like adopting both gender roles.. so essentially I'm not sure a mixture of the two genders accounts for a third gender, but then again, genders are socially constructed so I guess researchers will figure this out sooner or later. As for hermaphrodites or pseudohermaphrodites they can simply choose which gender they identify with the most.
