I'm absolutely a trans ally but what I don't understand about how science defines the sexes without reproduction. If those mushrooms have thousands of sexes, must they participate in gigantic fungal orgies every time they reproduce? Of course given that fungi are in an entirely different kingdom than mammals, I wouldn't be surprised if how sexes are defined is entirely different and irrelevant to how they're defined in animals.

My biology education ended at high school and unfortunately it was a high school that taught that the earth was 6000 years old so to say it was lacking would be an understatement.
