People who do not control themselves in public make me emotional. People calmly explaining to me that the earth is flat, people nonchalantly expressing agreement with Nazis (even though I'm part Jewish, though they don't know that), do not make me emotional. People getting emotional and using what I consider to be dishonorable, cheap, childish tactics in conversations offends me more than listening to even idiotic nonsense or morally reprehensible speech. I actually find myself feeling offended and getting emotional. I despise people who lack impulse control and do not control their emotions in public.
Two people screaming at each other makes me more uncomfortable than two guys punching each other in the face. Another thing, is that even in a conversation that I am not involved in and do not give a shit what the people are talking about, I feel disgusted when I see someone use the "cut them off at the pass" routine and respond to what the other person is saying before they are done talking in a not only dishonest, except more importantly cheap and dirty manner. That person is more deserving of a punch in the face than someone who calmly states that such and such group of people should be eradicated. The former is more dishonorable than the latter. It is like not following the code and taking your 30 paces in a duel.
When someone states even incorrect facts, they can be fact-checked. "Strong Opinions" are offensive because they can be pulled out of thin air and can not be quantified and tested, yet people sometimes give weight to them. Nothing is legitimate until we can measure it. Morality is the only gray area I can see and is tough to think about or discuss.
I cannot fathom how a calm, dispassionate turn taking conversation is not superior to any other form of verbal communication in every single imaginable way. It is the best we can do to try and eliminate emotional outbursts and psycho-drama bullshit. No yelling, no interrupting, and no displays of emotion. I have a hard enough time communicating the way it is without dealing with behavior that makes me feel nauseated. Who knows, perhaps those of us not gifted in the area of communication skills are better off not interacting too much with people who make us want to walk away from them.
