Deliberate use of fallacy

[GrandizerII]

If you know your opponent is ignorant use it - I used lots of fallacies in my course about debate and communication - In fact what I've learned is that convincing the audience and winning matters more than using rational arguments.

Always know the audience, their age, literacy and political opinions. Manipulate them. That's how you win

Really? Maybe you can start http://www.dystopia.net: The Dystopia Foundation for Sophistry and Science

Thankfully, my experience is that most atheists would find this approach shameful and counterproductive. Could you imagine a person trying to prove evolution using anything but scientific investigations? How would that help anything?

I agree with you that it's shameful to do so regardless. But that's what non-academic debates are about.
