So what?
I will add that I think teaching that way isn't great. Talk about males and females, penises and vaginas, sperm and eggs. But also mention that transgender people exist and such people as for example transgender men that may have vaginas can give birth too, etc. No need to spend a lot of time on that, but there is no reason that students shouldn't be taught facts in a comprehensive way. Given that transgender people are the number one target of American fascists for scapegoating, I think society owes it to youth to teach the facts about transgender people in an objective way free of ignorance and hatred.
