I dislike conflict.
No, that is not strong enough. I greatly dislike conflict.
I have always been this way. My mother tells the story of me, as a young child, trying to calm down my friends when they would argue. I would go along with something I did not want to do, just so there would not be an argument.
These days, I will leave the room when politics are discussed. Even if I have a strong opinion, to me it is not worth the fight. If I post something on Facebook or Twitter, and the result is a heated debate, I will delete the entire conversation.
