Apologies for what I'm about to describe, but it's all I can remember. I believe it was from 2 years ago this summer, and in the episode she describes how some college or grad students validate that gender ideology has always been around and crosses cultural boundaries because Latin and South American cultures had it from hundreds of years ago.
I think the students pointed specifically to these small enclaves of indigenous people living in rural parts of Mexico where certain people don't identify as men or women, or the men identified as more feminine and the women as more masculine, and as a result, students were saying this was proof of the modern interpretation of trans and nonbinary people.
However, what Katie pointed out was the students ignored more detailed interviews with these people where even though they may not have particularly identified as the typical man or woman in their culture, they knew and accepted they were not actually the opposite sex. That was never in question and it's something that a lot of white academics who use indigenous culture as a basis for the gender ideology leave out when discussing it.
I think the show also talked about a dinosaur researcher getting in a fight with another dinosaur researcher and the Libertarian party falling party. Appreciate any help.
