Sometimes, on the Internet, I see things about people "shaming" other people about you know, whatever. I've even seen these people referred to as "shamers." This is an unnecessary, watered-down word. There is already a tried and true word for people who harp on others in this way: those people are "assholes."
I am the author of 5 books: Android Down, Firewood for Cannibals, The Cubicles of Madness, Robot Stories, and most recently, Various Meats and Cheeses. I live and write in Michigan.
