Sociopaths very rarely have cohesive thoughts which can be used in debate or discussion. They simply attack you if you disagree with them. It’s kind of their deal, and forms the core of why people tend to steer clear of, make no eye contact with, or interact with insane or unstable individuals. Most of these poor souls don’t know they’re lacking in the critical thinking department and often react viscerally and intimidatingly, or even physically as a conflict resolution.
Which brings me to the contemporary Liberal: They attack you if you disagree with them as well, but there’s a distinct difference in most cases. They know a reasoned discussion will result in their position being exposed as myopic, loaded with unintended consequences, or even insane when the “repeating the same behavior and expecting different results” adage is applied. I say “most cases” because Liberals are known to use extreme intimidation, threats and even physical violence as conflict resolution as well.
I’m not going to bore you with examples, but Google the names, Kenneth Gladney, Allee Bautsch or Congressman Bob Etheridge for fodder. If that doesn’t get your blood running, try Christopher Dorner, Shawn R. Christy, or Theodore Kaczynski if you need your Liberals a little more extreme.
