These are home grown communists. Remember in the early 1960's congress did a study on the communists. Their manifesto was to get kids involved in drugs and sex (in order to control them). Get kids interested in alternative sex lifestyles, gay, lesbian, poly, swinging, living together, etc. This is to break up the American family through porn, womens lib, and the mentioned deviant lifestyles, etc. (more controlling especially women who didn't have a husband to provide for her). Take over journalism. Take over the schools. Push for universal government controlled health care. Get people away from God and church, even by becoming pastors or priests especially in more liberal churches). Take over one of the political partys (Democrat for sure). Make the government spend too much especially on welfare, food stamps, child care, etc. (This makes people dependent on government). By making the government spend too much it will collapse under the debt and they can come in and take over making a socialist state. Push a graduated income tax to tax the rich. Cause racial strife, age strife, rich-poor strife. By making everyone hate each other, it helps them take over to bring solutions. Take over the justice system to render rulings favorable to socialism. Have people question the constitution, our founding fathers, etc. Show the bad in our founders regardless of the overwhelming good they did.
America has so fare shrugged off most of this through the shear strength of the capitalist economy and through true Christians resisting the overwhelming evils.
I believe Trump is our last hope to save America. 40% of Democrats now favor socialism as being "more fair" to everyone. They forget upward mobility, and rising standard of living as well as Jesus said "the poor will always be with you". Even our American poor are = to European middle class, by means of home sizes, whether they have vehicles, washers, dryers, refrigerators, TV's, radios, etc. They forget that.
