Why have they been so effective?
Why have we as a citizenry been so "blind" to the presence and actions of these enemies?
@EdJames A couple of wise men once said:
America will never be destroyed from the outside. If we falter and lose our freedoms, it will be because we destroyed ourselves.
Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free.
We've been blind because while we were busy leading our lives trying to do for our families the best we could...there's been a cancer developing from within with names like "inclusion"..."social justice"..."political correctness"..."speech codes"...and on and on and on...it's eating away at the very fiber of what has made this country great...by indoctrinating generations into believing that everything good about Americans as a people and America as a country is somehow bad and wrong. At first it was easy to laugh off by most because this kind of foolishness was viewed as just a handful of crackpots looking for their 15 minutes of fame.
But to borrow from an old Reagan campaign ad:
There is a Bear in the woods
For some people the Bear is easy to see
Others don't see it at all
