I wonder how the high school cheerleaders in Kountze, Texas, would react if a Muslim student wanted to have the football team run through a banner festooned with quotations from the Koran. Would they support that individual's right to free speech, or would they consider it an affront?
This likely contradiction is the reason the U.S. Supreme Court has ruled that public school-sponsored religious expressions are constitutionally prohibited. In a free and open society, you cannot have it both ways.
Matthew 6:5 states: "And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by men. I tell you the truth, they have received their reward in full."
