There are 2 genders.

Gender is both a spectrum and a social construct.
There can be as many genders as there are people.

Just Respect People And Their Prefered Pronouns.
Don't Try To Make Them Fit Your Own Boxes.

(In case you or your browser has scripts disabled, the number of genders at the top of this screen is set to count up rapidly after a second to make the point that the exact number doesn't matter in the slightest.)
