I've noticed that I get pretty defensive when people come at me aggressively, yet on the flip side I absolutely hate confrontation and try to avoid it at all costs. I also try to be reasonable and fair. I just don't feel as able to stay calm when I'm around very angry/aggressive people even when the topic has zero to do with me. Ex: Sports, religion, politics, whatever. The topic isn't important. It's mainly the tone of voice being used and their body language that affects me.
