Before we get all high and mighty over the swearing by the student section, recall that during the first OU game after the 2005 MAC championship game, there were long stretches of chants of "F Ohio". I do recall Reggie taking the mic a few times before games encouraging the support, but discouraging the cursing and off-color heckling.
And I'm not defending the cursing- I thought it was dumb back then when I was in the middle of the Student Section, and still think it is dumb, especially now that I have kids with me at most games.
