One girl said to me at the beach that everything depends on from whom you learn. This was prompted by another girl saying she was majoring in criminology and gender studies where upon I explained about the Frankfurt School and the roots of woke and gender ideology. The students listening had never heard any of that. They had thought gender stuff had emerged full grown like Athena from the forehead of Zeus.
