In any case, instead of the discussion going so far as the teacher threatening to send the students to the principal, they should've been more respectful of the teacher's position of authority, not argue with him and taken their concerns to the principal's office themselves. Or it's possible he was trying to see if anyone would respond to the incorrect display. However, education and counseling programs, although helpful, aren't the ultimate answer to school violence. Our educated society is proof of that. Neither has the capability to change people's hearts.
Education is no match for a heart filled with rejection, hatred and bitterness.
Only God and his love working through people have the power to truly change hearts, replacing hatred with love. Allow the Bible back in schools. Then you will see lives changed, or slowly watch our rapidly becoming pagan nation destroy itself. Pray that enlightened, new judicial appointees will interpret the Constitution as our Founding Fathers intended. Whatever the reason, the captain is responsible for the ship.
