Would you like to have a big audience show up for your next speech? 

I  mean, would you like to have the room filled to overflowing? It turns  out that this is actually fairly easy to do: just agree to give a speech about a controversial topic,  you know what I’m talking about: sex, religion, or politics. The reason  that so many people are going to show up is because a lot of them are  going to disagree with what you have to say. 

Just exactly how is a  speaker supposed to go about giving a speech like this?
