It is inevitable. A columnist will post a thoughtful article on a polarizing topic, and the comments section will explode. Whether the column was sensationalizing one side or the other, or if the columnist took a more moderate stance, it doesn't matter. Often, the commenters have obviously not even read past the headline. They see the word that sets them off, that raises their blood temperature to a boil, and they have to attack. Or they see their side being razed, beaten down once again by the mindless cretins who are always on the attack. They charge into battle, swinging blindly and hitting whatever stands in their path. In the end, the same thing always happens. The argument goes meta, and becomes about arguing itself. Then, someone brings up Hitler.
No, wait, not Hitler. I meant Linux. Somebody brings up Linux.
