Okay, I must be missing something.
Maybe we need to define the term "anecdotal." Are you saying that the Cornell burnings were hearsay, or rumors? That it didn't happen? Are you implying that because these people have opinions, that therefore they must be making up all this stuff? Or maybe we are only hearing one side of the burning of newspapers with incorrect opinions, and we should be hearing the other side of the story.
An "editorial" on a subject does not mean the subject is fictional.
And I challenge you to find one example of a leftist being heckled in an organized manner on a college campus before September 11.
