If Lucas had deleted midichlorians, "ex-squeeeeeze me", poo jokes and fart jokes from the movie, I firmly believe fans wouldn't have been so hostile. They may not have loved the movie but those things seem to be the common denominators that pushed everybody over the edge. It's the difference between mob unrest and a full scale riot. And, speaking as someone who enjoys the prequels, those things are indefensible. Maybe the whiners did behave like children but you can't argue they didn't have a point at least on those elements.
