The place to start is to eliminate the liberals from school boards. That is where to begin. My grandson will be changing schools because the Superintendent of the school he was attending has been replaced through some school board shenanigans. That Superintendent was the first educator I had met in years that I liked. He was fair, had a good handle on the students' needs, and is being replaced by career school administrator with a shaky track record. (Whom, frankly, I don't like.) The result will be a school which is no longer a good learning environment.
This principal should have received support for his actions, first defending the history of the city, the heritage of so many southerners, and the defense of a West Point Graduate who made the hard decision to fight for his native Virginia rather than take command of the Army of the Potomac--a matter of honor and not being a traitor to his native State at a time that marked the end of the Era in which States were regarded as Sovereign entities united in a Federation, not as subunits of an all powerful National Government.
