Describe Trump's Travel Ban: It's Stupid

To all the outraged blog commentators that slammed me for killing the economy by cancelling my Delta flight, I ask where's the outrageous on what our President has just done? Banning travel from Europe for non-Americans is utterly stupid. I don't know why I have to explain the obvious, but some ignoramus may think it's a good idea and may actually read this. The chances of convincing said person that I'm right is less than zero, but maybe I can prompt that person to give me a reason why I'm wrong.

First, the virus is already here. Blaming Europe or China or space invaders by issuing a travel ban doesn't solve the problem. Second, look at the Dow. Can you say calamity? Presidents are supposed to calm the markets, not set fire to them. Third, US citizens can still fly from Europe. Luckily, they won't bring in coronavirus because they are American.

The world needs collaboration. It doesn't need fragmentation. The world needs pragmatism. It doesn't need politics. The world needs a leader. It doesn't need Trump.
