If you have enemies you do not hate them, because controlling your hatred to weaken you in your rationality in analyzing things, prevents you from thinking clearly in their real weaknesses, and fill your mind with emotional illusions by saying that they are stupid or evil, and he turned all your analyzes to justifications, It is best to simply try to understand them as diligently as possible, and then hit them at specific weaknesses over a possibly broad time, if you want.
