In the recent decade, scientists have moved away from the general concensus we all learned in high school that there are only two genders: XY for males and XX for females. ie. there are people with XXX chromosomes, and more.
Increasing evidence has been mounting over the last 10 years of research and studies, that what we considered "genders", is actually a spectrum.
Does anyone here get a bad taste in their mouth when they read this or learn about this? Looking at the video's dislike ratio, I'm sort of curious why there are people who find this offensive rather than think wow that's cool.
