I agree. Anonymous notes in letter boxes tend to be inflammatory in my experience. Anonymity removes a pressure to be scrupulously fair and accurate in the contents of the communication. Being fair gets respect and good results eventually. Backing off just to keep the peace can make things more comfortable in the short term but stores up problems for later and trains the noisy minority of bullies that they can get away with being selfish at the expense of the quiet majority who would rather not stick their necks out.
