I watched this earlier today and it was crazy how there were so many different answers to what sounds like or should be an easy question. But then again I think some of the people in the video were drunk. There were a couple people who immediately got defensive though, like "Why are you asking that question?" "We all deserve to be alive" and somebody just straight-up said "No."

If I were at a public event like this and someone asked me how many genders there were, I probably would have said something like "lots" or whatever, even if I do know but don't want to give a "wrong" answer and have someone try to fight me over it.
