I do tend to feel a lot of aggression but its more often not speech related. I have road rage as well. yesterday someone was driving crazy and almost rammed into me so I lay on my horn and the guy opened his car door too come for me! Oh big mistake- I screamed at him and insulted all his god, his dog, and his mother so thoroughly I started laughing and said sorry. But I was really upset that he tried to frighten me. I am aggressive, I am short, it's like genetic or something.
