Logical debate is a necessary part of every activist’s life. But before engaging in a debate, make sure you ask yourself the following questions:
1. Do I know the subject? – For seasoned activists, this should be a given. But for newbies, it is normal to romanticize passion and equate it with victory. If you don’t think you can pull it off, leave it to the experts. If you think you can, make sure you have information handy.
2. Are my objectives realistic? – If you are about to argue with a religious fundamentalist with the intent of convincing the person to turn against faith, you might as well argue with a 10-foot tall slab of concrete. As a personal policy, I never engage in debate to win. I engage to educate and to learn.
3. Are we both clear on the parameters? – At the onset, make sure both of you know the rules. I generally do not engage if I know that Bible verses will be used against me. It defeats the purpose of a logical debate. But for some people, that is perfectly fine. So know what parameters work best for you.
4. Can I document the whole discussion? – If you can’t document the discussion, then be prepared for a lot of moving goalposts (discussed later). Documenting the discussion ensures that both of you have a way of getting back on track. It’s also a nifty way of catching contradictions.
5. Will this do more good than harm? – Sometimes, winning an argument will actually put you in a worse position or result in more damage to your cause. Be selective. Choose your battles.

If you answered “yes” to all these questions, then I present to you ten commonly used fallacies and what to do when they are used against you in logical debate (actual quotes from actual debates are found here).
