Their goal has always been the destruction of the US, from the get-go.
They were correct in their evaluation and very successful in their plan. They use the freedoms of this country to destroy those freedoms. They use our money, via government jobs, union dues, taking over foundations, trusts, etc., to do it.
We all need to dig up these facts, such as you have done with the ACLU, and see that they get wide exposure. The birth of labor unions, the Frankfurd Group, etc., are examples. David Horowitz does a lot of good work also. We need to reference him often.
There are too many people today who were educated by the leftist schools and the MSM, and far too few who remember the lessons learned in the '40s and '50's about Communism. Today is a replay and acceleration of the tactics of the '60s.
