No, that has nothing to do with it.
I just think if you're going to rule out biology, and pretend gender isn't binary before birth within animals and plants, then you're basically going by germs or fungi reproduction, which have no gender. If that's your philosophy, then okay, but to deny science means you have some sort of angst against whichever gender you have and just want to make it up as you go along.
**** it, I'll be red gender and you can be green gender. Which one is the bottom? Oh it can be either. Let's be the left and the right. Wait, isn't that offensive to left handed people or ambidextrous people? No because biology isn't in your ****ing lexicon. Let's just make it up!
