I watched recently the outstanding documentary "Rod Serling: Submitted for Your Approval". Produced in 1995 for the PBS series American Masters, this 90 minute film is recommended to anyone who fights with and for the creative process, especially one attempting to fuel a commercial form.
Mr. Serling was known for his 'can opener' opinions, like this one:
"I happen to think that the singular evil of our time is prejudice. It is from this evil that all other evils grow and multiply. In almost everything I've written there is a thread of this: a man's seemingly palpable need to dislike someone other than himself."
In this Age of Trump, a comment like the above contains fortified resonance.
