Your bizarre justifications of what Trump does are hilarious. He shut down flights from China while the USofA was getting the virus from Europe. That’s useful!
I also criticized other actions Trump made in the same post. Your argument is that Trump is 100% wrong 100% of the time, which is obviously illogical. People's hatred for the man get in the way of their common sense. Policies are not to be judged based on how much you like or dislike the person enacting them, they should be judged on their own merit.
Trump shut down travel from China first because the outbreak was there first. Trump publicly said he was considering travel bans from Italy and North Korea on Feb. 27. Trump later shut down travel from all of Europe, starting with the Schengen countries because they have an open-travel agreement, a couple of days later the UK, Ireland etc. He did all of this before Canada had ANY travel bans.
That doesn't mean I think his overall response has been good, because it's been pretty bad. But credit where credit is due. Trudeau performed worse than Trump in the beginning, but has acted far better since. Credit where credit is due.
