Today some of America’s least free places are many government schools where students enjoy less free speech than prisoners since “zero tolerance” and “social justice” trump liberty.

The same month an 8-year-old Scottsdale, Ariz., boy was suspended for drawing a ninja, a Star Wars character and a soldier.
