On the internet everyone’s an armchair quarterback ready to leap into a conversation between two strangers to insert their opinion or correct the facts. The problem is most people aren’t as smart or knowledgable as they think they are and, in the rush to puff up their own egos by being right, often get it very very wrong.
One of the most satisfying genres of people stepping on online rakes occurs when someone tries to school a stranger…only to discover that the person they’re correcting is actually the actor/director/author/historical figure that they’re basing their incorrect opinion on. Sometimes these instances of mistaken identity are perfectly innocent whereas other times comeuppance are deservedly delivered.
In those cases the self-own factor is off the charts and it’s just so satisfying.
