Twitter is where you go to find out how rancid some people are deep down. Twitter is a social-media form of those ugly-truth-revealing glasses that certain characters put on in “The Cheaters,” that 12.27.60 episode from Thriller. Twitter is where you find out how small, smug, lazy, stupid, tedious, hateful and sometimes even disgusting people are. Twitter has brought to me to places I never knew existed and am now very sorry I know about. The loathing I feel for those strutting, shrieking, foo-foo Twitter scolds out there sometimes manifests into stomach acid, indigestion, headaches and God knows what else. It’s all I can do to keep from spitting on the floor.
