The bossiest, smuggest, preachiest, most didactic people I know are the ones who are Green, and who want everyone else to go Green, too.

They are the new fundamentalists, the new Sermonizing Class. They are what so many preachy Christians, by and large, used to be in the culture and in the workplace (and some who still are), always quick to point out what someone’s doing wrong: why regular milk has too many chemicals, why driving your Taurus is bad for the environment, why your clothes could have been made of organic cotton.

They think they’re educating you. But as soon as you make a joke about the milk, they don’t laugh. That’s because one problem with all passionate, argumentative fundamentalists is that they cannot laugh at themselves. Global Warmers and Climate Changers don’t know how to laugh.

As a Christian and a young playwright, I struggled with how to write about Christians in a comedy. What would people say if I made fun of them? What if I point out the ironies and contradictions of the church, or a Christian character

Now, of course, I know the answer: it doesn’t matter. My job, as a comedian, was not to protect a certain class of people (Christians, or Climate Changers, or whoever). My job was to write things that were true, and because they were true, they were funny. We just happen not to see too many satires and jokes about Global Warming because too many of the people who write jokes believe in the stuff.
