Long ago, someone asked me straight up if I believe I know everything.  I flat out told him I recognize my own humanity and fallibility.  Either you missed that or you don't care.  Of course, this overlooks the simple matter that it doesn't take omniscience to recognize someone presenting a patent error in a statement if not outright lies in a political (and often partisan charged) discussion.
Now, do you have something to add to the discussion about the travel ban or should I consider you as part of the same group as Kon, ie. trolling?
