From the linked article in the OP, regarding the Jags owner citing Martin Luther King Jr. as an influence:
So let me respectfully challenge Mr. Khan to consider these words from Dr. King: “There comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must take it because conscience tells him it is right.”
How is this issue an ethical one? Only if one takes the stance that Tebow's banishment is due to his religious conviction, which is most certainly not the case. I'd wager Chuck Norris wouldn't be commenting on Tebow if he were openly an atheist.
