I checked it out. was interesting. but it didn't convince me that there are over a dozen bloody genders.
there is male and female. and I am willing to believe some people due to hormones or some other twist of fate end up having a male body, but identify as female and vice versa, and I suppose you can call them transgender and make it a third gender. but i don't believe there are over a dozen different genders simply because some people "say" they identify as that gender.
if i said i believed myself to be quadgender , that DOESNT mean there is such a thing as quadgender. a LOT of these "genders" on that list could be lumped together due to how similar they are.
