I can't recall where I heard this:
A woman was taking a Japanese Shihan's seminar somewhere in the USA. She heard him say, "Aikido should be done with arrogance!". It was a bit shocking to her, but, as it was his seminar, she decided to give it a try. It worked wonderfully. Her techniques started to flow. She felt really in charge and everything went great. After the class, she went to her Sensei and told him about her breakthrough. He looked at her and said, "He said that Aikido should be done with elegance.".
As for tactics to deal with intimidation, you can always try the Cyrano method. You not only agree with them, you expand on the attack. Sort of like completely going with the attack. Kind of like Aikido. Exactly like Aikido.
