I've noticed that after you get into an argument of some sort with someone, you tend to laugh more (in a bad way) when asked about the person(s). For example... John gets badly beaten up by a group of Mexicans. After that, Jane tells a joke that would be considered racist, but John would laugh. Or, Joe said something negative about John and this made him mad. John and Joe proceed to fight each other. A little later, Jane says something like, "Joe works at a strip club!" John LOUDLY laughs about this, even though John knows Joe really works at a restaurant.
So does anyone know what the exact word be for this kind of thing? It's not exactly racism, but I can't figure out what would be a good word to describe it... (if any of that made sense) Any suggestions as to what this might be called?
