Quite a few lessons here for the ones with eyes to see: 1. Differentiate between what you know and you don't. 2. If you think you know something from internet, from media or from gossip, it means you do not know it. 3. About things you do not know do not use incendiary language. Never use it, unless you know what you are doing. 4. Never attack the messenger. Instead, if you are out of arguments, admit defeat or go for the bushes or both.
