What harmful language? That which limits or "harms" state power? How about this line

"That whenever any Form of Government becomes destructive of these ends, it is the RIGHT OF THE PEOPLE to ALTER or to ABOLISH it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness."

If you are corrupt government, that little passage might damn well seem "harmful."
