The best way to do that is to call them what they are: COMMUNISTS!
It time for them to be in the defensive position of having to explain why they are not communist.
That's definitely where we need to start, but before that can even happen, Republicans, conservatives, and patriotic Americans are going to have to all come to grips with how perilous our situation really is.
We're going to have to stop doing whatever we've been doing, if we want things to change. In my mind, that means real, and unrelenting activism at every level on our part. It's going to take an unprecedented effort on our part to steer the ship back on course.
