If they have been employed more than 2 or 3 years, if they are not warning every parent they see to remove their kids, if they are not seen protesting the union mobs, then they are part of the problem. They are enablers of evil.
My decision: I shun these people. I will not have a government school employee for a friend and work to keep them out of my life as much as possible. They are too evil, too stupid, or too much of a well-meaning Useful Idiot to be a friend.
A lot of those folks are trying to buck the system as best they can. Many get out once they see what is happening, explaining why more than half do not stay beyond five years.
