I'm not going to tell you anything about your own country, but at the turn of the century, when I was studying in Tokyo, I met an Australian for the first time. A fantastic girl, truly awesome. Very progressive, but so was I, as a libertarian.
I remember laughing at her because she was majoring in "gender studies" and she went on to write her PhD thesis on something like women's treatment in Japanese folk stories of something like that. I had never heard such bullshit, but I simply dismissed it as a harmless oddity.
My point being, shit doesn't happen all of a sudden.
