I’m going to write more about this later, but can I just say how angry it makes me that we censor people’s right to sexual expression? As sexual beings (our primary biological function is reproduction), the most pure form of expression we have is sexuality. If you want to really understand humans, you have to understand the way they express themselves sexually, and when that expression happens in exceptional ways, it is worth encouraging like all exceptional behavior, rather than working to stifle it.
And watching the way a culture’s sexuality evolves will tell you more about them as a people than most other factors that we take seriously in my opinion.
