This is obviously BS, since gender is a social construct.
Gender is. Sex isn’t.......................
Supposedly, those people who claim to believe in science, liberals, are the most anti-science people in these types of studies. Driven by decades of pushing the bogus blank slate (tabula rasa) theory and equally moronic feminist theory of male/female differences, millions of libs taught and believed those idiotic ideas.
Head radical feminist Gloria Steinem was emphatic about claiming men and women were exactly the same except for some "minor" physical differences. As far as explaining human and sex differences, liberals are clearly the stupid, anti-science people.
