I was recently taught the genderbread person in a healthcare college course completely unrelated to anything trans/identity/whatever. It had no relevance at all to what we were learning, but the teacher inserted multiple slides to lecture us on gender and identity in the first ever lecture of the class.
In my class reviews at the end of the semester I'd like to include why we shouldn't be teaching the stupid genderbread person in this class, and am looking for arguments/resources to refute it, as it seems like subjective pseudoscience to me.
Edit: I've looked more into the image and it's just artwork created by a trans activist. But I'm wondering what actual science it is referring to?
