He could write the line on twitter "My fellow Americans..." and doomers still gonna doom because they are fear addicts. Shills are their dealers. As Rush Limbaugh once said "It takes work to be an optimist". You have to think rationally about things.

Pessimism and complaining about how you are scared and miserable are easy. It is giving into irrational and emotional thinking. If you try to talk them out of their fear with proofs and evidence that shows their fears are not true they actually get upset. I also notice that doom and gloom people LOVE transferring their misery onto others. I guess misery really does love company.
