When? The 60s. The beatniks from the 50s had started to raise their children to think in this mind set, giving us the hippies in the 60s. The Communist capitalized on this new generation of looser and began to infest our education system with 'teachers' who would begin to teach students that America was bad. Useing the Vietnam war as a catalyst. The hippies of the 60s then went on to raise their children to think the same and so on. As the commies power in the educational system grew they began putting hippies into teaching positions. These hippies where able to use unions formed by said commies as a way of protecting themselves from termination and became more aggressive with their teachings.
This did not happen rapidly, it was generations of brainwashing of which the seeds where planted in the 50s and began to bloom in the 60s as 'flower children' came to age.
