I am in the process of grading essays about sexuality and they range from the absurd to the sublime. Sexual organization varies from culture to culture and is so deeply embedded that few people really stop and question why we think about sex the way that we do. So, when you ask someone to give a social analysis or interpretation of a sexual behavior (oral sex) or identity (heterosexual) most people fall short.
Somtimes, the claims are simply weird:
Homosexuality is not practiced as widely as it was in the ancient days due to the evolution of the human brain…
This is a thesis statement in an essay. My polite response?
Be prepared to back this up with evidence.
Perhaps people are conflating opinion and evidence. Considering that a certain network television show likes to call hidden camera shenanigans “experiments” I can understand how this confusion could arise.
