In regards to your second and third question, I guess so though I'm not sure. If I understand you correctly, it sounds like you're referring specifically to threats of action which are either hostile or brash, or otherwise harmful. Basically, a warning to others that you are about to "make a point" and it's not going to be pretty. Yes, I find myself doing this when I get angry from time to time however I don't always give warnings when I'm about to take action. What you're pretty much asking is if I tend to get people "on edge" when I'm angry. I mean, when I'm pissed, I do want everyone surrounding me to be angry as well but I don't necessarily intentionally put them on edge everytime.
No, I do not like fucking with people like that although I can understand why you'd find it amusing, if you do.
I suppose I can agree with viewing control and power as a means to an end however there is something about the allure of power that motivates me to acquire it and wield it as more than a means to an end. Yes, my tritype is 8w7 - 7w8 - 3w2.
When I happen to be angry with someone who is actually present in my surroundings however, I definitely do not avoid eye contact. Quite the opposite actually, I stare them the fuck down.
