At what point, my friend, are fear and anger appropriate?
In politics? Never. Be smart always. Fear and anger accomplish nothing.
But as I said, if you enjoy being goaded into fear and anger by political theater and the media, then have at it. The sky might certainly fall someday and it's never too early to run around shouting warnings in all directions.
But if you don't mind, I'm going to remain calm and see what actually happens.
