Yeah, calm the f*** down. If the quote hadn’t been attributed to Cosby, you would probably have called it a great parenting quote. You just pounced on a teacher, without warning, with fangs and claws bared, for correctly attributing a quote. Great job, take another bow in thus public forum, while the crowd goes wild. It’s probably the case that Julius Caesar, Sun Tsu, Attila the Hun, and Adolph fucking Hitler said things that were interesting, independent of their infamy or not. And if they did, it would be correct behavior to attribute the quote to its author.
Not a fan of Cosby, by the way.
