The problem is that there are some points of view that should not be respected. Hitler's point of view was that the Jews were a menace and had to be eradicated. I'd rather cut my own throat than respect Nigel Farage's point of view about immigrants and I will not respect Trump's point of view about Mexicans. There are some points of view that should be severely challenged, not respected, and there some which should be rejected outright. Our problem isn't that we should respect all points of view. Our problem is deciding which ones should be kicked out the door.
