It's much easier to write a solemn book than a funny book. It's harder to make people laugh than it is to make them cry. People are always on the verge of tears.
I've reported in countries where leaders not only complain about a critical press, but also try to shut it down, throwing reporters in prison or worse. I've seen my colleagues risk their lives and, with increasing frequency, lose their lives in their pursuit of the truth. We are not about to stop doing our jobs because yet another president is unhappy with what he reads or hears or sees on TV news. There is a reason the founders put freedom of the press in the very first amendment to the Constitution.
