I blame the Huffpo. These narratives are their bread and butter and that site is incredibly popular with liberals. Its odd that liberals went from their 60s era 'freedom from authority' ideals to becoming authorities themselves and engaging in exactly what authorities back then were doing: being overly moralistic, shaming sexuality - especially for boys, creating narratives of 'the other,' being dishonest to win political points, shaming/chiding for social control, etc.

The Huffpo is about as far as you can get from the Summer of Love as humanely possible. Regressive liberalism is a real thing and barely recognized. It seems liberals have very much bought into shaming and apparently it gets results (ad revenue, facebook likes, etc).
