Thank your local school teachers, and the Baby Boomers that embraced socialism during the 60s and then turned into the school teachers and college professors of today's public school teachers.
none of that was an accident, or occured by happenstance. Communists had a long range plan. Back right after the Russian Revolution, they began to infiltrate politics, colleges, unions and newspapers. Keeping mostly in the back ground at first, they burrowed into government at all levels.
The Red Scare of McCarthy had a lot of basis in fact.
After a generation or two, those that think communism is the answer have about taken over education, foreign policy, entertainment and news.
If you have not already boned up on Saul Alinsky,s "12 Rules for Radicals", you are behind the curve.
