The problem is, I was/am a very manipulative person by nature, so I really need the conscious overcorrection. Whenever I detect within myself a desire to change someone's opinion, I know how much it weakens my defense against making bad arguments. It's like writing emails late at night: in the process of doing it, I like the resulting text just fine, but I know from experience on a different level that I'm going to be ashamed when I reread it in the morning.
