The Public School system was stolen by the far left and turned into a leftist, hyper-humanistic, amoral indoctrination camp.
The fruits of this coercive system has moved the country further and further away from the values of the parents and toward the values of the liberal and godless left.
A true leftist wouldn't punish a student for a "Bong hits 4 Jesus" banner. Rather, this is a government school vs. free speech issue. And with this ruling against a student who was not on school grounds, and on his own time, public schools just moved a step closer to being awarded jurisdiction over all time and space. Not cool.
