That's not what he said though. He said National Intolerance Day.
On a day devoid of any groundbreaking or utterly stupid proclamations from either candidate, what was occurring Nationally? What was beginning to dominate the news? Chick-fil-A appreciation day. I contend that Mr. Shepard was intimating that event as being intolerable.
If he had meant what you are saying he is right about, then why didn't he say that? Being clever for our entertainment should be reserved for the job title of fool, not news journalist.
