Given that it took about two centuries for the public to accept the heliocentric model, some patience may be needed. A great number of people only learn about gender through undergraduate education. And, iirc, only 25% of the population have undergraduate degrees.
Heh, I can't tell if the downvotes are pro-gender studies, anti-gender studies, or just don't want to hear about gender studies.
I've never read an explanation of gender that couldn't be summed up as "one's personality".
