You must not have been in the same locker rooms I’ve been in. Or owned the same dogs and horses I’ve owned. With rare exceptions due to genetic problems, there are two sexes.

Put down the bong! BEFORE Leftists started destroying society, Social Conventions were premised among primarily Natural Law and Self Evident Truth. In Biology (Physical Science) the discussion of sex is all about procreation. The Human species is heterosexual; in other words procreation is accomplished with TWO sexes, male and female.
Terms like Homosexual and Transgender are subjective (Mental Science) social constructs created by Leftists.
