Universal declaration of rights of the howlers:

Article 1. All human beings are endowed with the god-given right to make firewood from the fallen tree. Article 2. Any tree will do. If it is tall, it should be cut down. The quality of the wood is no matter, the tree asked for it by growing tall. A decent public will cheer to see it toppled. Article 3. Rules of normal kindness do not extend to the celebrated person. Article 4. All persons may hope to become celebrated. Article 5. It is more important to speak than to think. The only danger is silence. Article 6. A howler must choose one course or the other: lie routinely, or do so only on important occasions, to be more convincing. (The Trotsky tenet.)
