"calm down, politics is the mindkiller"

Agreed. Of course, calming down is hard enough by itself without people seemingly actively trying to prevent you from calming down--people like, say, the commenters in that particular blog post. (Major kudos to DataPacRat for managing to stay calm while he/she was being accused of believing in "godbots"; I would not have been able to do the same.) I'm inclined to apply the principle of charity here along with Hanlon's Razor to conclude that they're not actually deliberately trying to piss you off... but God, it sure feels like it sometimes.
