Good satire comes from anger. It comes from a sense of injustice that there are wrongs in the world that need to be fixed. And what better place to get that well of venom and outrage boiling than a newsroom because you're on the front lines.
What is tolerance? It is the consequence of humanity. We are all formed of frailty and error let us pardon reciprocally each other's folly - that is the first law of nature.
