I had a hippie teacher in the 70s who taught a current events class. One day for illustration purposes about some point I have since forgotten, he used a current candidate for Congress as an example of some kind of evildoing. He stipulated that he did not know if that candidate was actually guilty of the wrongdoing he was saying, but he went on to paint a very negative picture of that candidate.
That candidate was a Republican. And it so happened I was on his campaign staff.
So I gave my teacher both barrels.
