I can't tell if you're being sarcastic or not. But great presidents don't try to undermine what makes our democracy work.

Look at Obama - he was accused by the media of being a muslim and not even a U.S. citizen. Did he demand everyone ignore the media? He didn't. Was he a perfect president? No. But his differences lay with policy - not with treating anyone who disagreed with him as un-American and his enemy. 

It's a pretty low bar, I admit. But him and most other presidents have been able to at least keep that bar set.
