college professors and teachers......
lets go ask Bill Whittle. He has a very good indicator of the wave and flow odf the medias and how outside ideas critical of America found their way into our culture... via the TV. When we developed the technologies, we were a net exporter of american culture. As the rest of the world learned they could communicate, they started having hollywood create movies based on their biases specific to their target markets and sell them to us, the tide switched. Then the marginal idiots bought into the ideas and conspiracy became the big conversation piece for the unknowing, thereby shaking our core beliefs.
It is this which helped propel a alien asshole into our white house.
