I go ya one further.
The American Left are admirers of all things totalitarian because other totalitarians-Castro, etc...have been able to do with their dissidents (kill and imprison them) what the American Left would do to Flyover Country if they could. The American Left are a bigger threat immediately than ANY Islamisist because they enable the Islamisist in our name.
Marxism is our nation's greatest threat. It is occupying center stage. (Islam is waiting in the green room.) The Marxist left would kill us if they could. They just can't get away with it....( yet.)
And...The Marxists' most powerful weapon against us is SCHOOLS! (kindergarten through graduate school)
