Aggressive questioner - Sometimes you encounter someone who is hostile or has a competing agenda. Instead of trying to learn, this person wants to undermine you, your organization, or your point of view. Lenny Laskowski of LJL Seminars offers some tips for dealing with difficult people and their difficult questions:

1. Prepare for likely questions before the speech.
2. Keep your answer short, if the question is a simple one.
3. Don't point or put your hands on your hips when you respond.
4. Wrap up the Q&A session with a concise restatement of your main point.
5. Answer directly, speaking to the person.

Mr. Laskowski advises speakers to listen carefully and repeat the question. This is a good idea in general, not just if the questioner seems hostile.
