A recent Rasmussen poll found that the majority of Americans believe there are only two genders. Isn’t it obvious there are only two genders? Even those who are gay or trans fall into the two gender category. Who are the minority that doesn’t believe in only two genders? They have to be flakes, and fruitcakes, and others who live in a false reality.
If I were religious, I’d say there were two genders since the time of Adam and Eve. If I weren’t religious, I’d say basic anatomy proves the two gender argument. Either way, there are only two genders and it’s obvious to most of us. Ignore the opinions of those that don’t agree. They are worthless dregs of society.
