One of the many problems with the American left has been its image as something rather too solemn, mirthless, herbivorous, dull, monochrome, righteous, and boring.

Christopher Hitchens was a renowned British-American writer, journalist, and literary critic. In this quote, he is pointing out the problem with the American left – that it often appears too serious and dull, lacking any sense of humor or fun. He is highlighting the need for the left to be less rigid and more open to having a good time. He is also calling for the left to be more creative and diverse in its approach to politics, as this will make it more attractive to a wider range of people. Hitchens' witty and humorous style of writing makes this quote all the more effective in conveying his message.
