"By the way, can someone please let me know when we can stop being diplomatically nice to Humphrey Smith, then we can ask John from Hull to send his letter"

It might make us feel better but it is extremely unlikely to help the situation and far more likely to harm it. Despite how we feel, Mr Smith is entitled to take this action. He is even more likely to feel he is right if he can demonise those who disagree with him because they have attacked him personally and/or publicly.

Let's just keep the adverse publicity going!
