That's Being Absurd(us)
The word "absurd" comes from the Latin ab.-surdus meaning "absolutely deaf." To fail to listen is to become absurd. On the other hand, obedience is from a Latin root, obaudiens, which means "to listen thoroughly."
When you are so wrapped up in preconceptions and prejudices that you cannot hear anything that doesn't agree with what you have decided is true, you are being "absurd". Truth doesn't need your anger to support it, truth speaks for itself. Any argument that is wrapped up in anger, ugliness, insults, and condemnation of anyone who disagrees with you is, by its very nature, flawed and without merit. Any "truth" that cannot survive an open and honest discussion is, by its very nature, not true. If you cannot discuss your beliefs reasonably, then perhaps what you perceive as "true" is no more than an ill-informed opinion.
Listening thoroughly, not solely with the intent of looking for a wedge you can throw into whatever premise is being presented, can open your world to new understanding. That change can be scary, we all know, but changing your perceptions of the world can be the scariest undertaking of all. However, choosing not to listen and refusing to even consider a different point of view does not make your opinion "true"; in the end, it only makes you absurd.
