When the valedictorian (or any other student speaker) is introduced, I don't understand why the introduction can't conclude with a disclaimer that the contents of the speech is not school sponsored. Problem solved.
They do that with TV and radio editorials all the time. Everyone understands.
Curious what the response would of been if they pull the plug on a "Gay Pride" event. So much for "Celebrating Diversity". One of the most obnoxious things about the Modern Political Left, their rabid hypocrisy.
