But when you use words like "should", you've kind of already accepted the fate that it is not.

There are fights worth having, and then there are fights that are worth walking away from. If someone starts spouting off garbage, I just walk away and cut ties with them. I'm well past arguing over stupidity. You can tell when someone is unreasonable pretty quickly. However, when someone responds in a way that says they are willing to at least consider an opposing view, I will have a conversation. I enjoy those conversations even if no view points are changed at the end. That's the way it should work. See, I just said should as well.
