I will debate any statist on any argument whatsoever, and I will destroy them (the argument that is!), and what is more, I will do so not only with real actual logic but as and when warranted with facts and references. And what is more I will be polite and will not resort to name calling or personal attacks at all, but will of course expect that same consideration in return. And I will win the argument, always, and completely. There is no argument for big government statism that can defeat me - because I am right and you are wrong.
Statists generally prefer one-to-many broadcast methods like the evening news to spread their (largely emotional, fear-based) propaganda. This way they know there will be no equal airtime given to someone who logically questions their proposals and looks at them with a critical view. They are too welcome in too many other, much more convenient forums to actually take up your challenge on anything like a level playing field.
Although, a favorite trick of some flavors of statist is to invite dissenters to call into the show. The host will mute the caller, talk over them, refuse to answer inconvenient questions, and usually entirely take over the asking of questions, respond to complex and nuanced issues by badgering the caller with a series of yes/no questions designed to lead to a predetermined conclusion (an abuse of the Socratic method), changing the subject ("We had no justification to be in Iraq." "Saddam was a dictator! Do you support dictators?!"), and use other propaganda techniques designed to appear legitimate. This will convince the naive that any debate is happening, and that no one can successfully get the host to admit fault because the host is always right.
In summary, you're not going to get an honest debate because these people are afraid of honest debate and go to great lengths to avoid it. With a mere five corporations controlling every major newspaper, broadcast TV news service, radio news service, cable news service, and online news outlets, there simply isn't enough diversity to allow for anything in the mainstream other than an echo chamber. It comes in two flavors: "left" and "right", which are two slightly different methods of reaching the same conclusion that the solution to our problems is to concentrate more wealth and power into fewer hands.
