The various governors and mayors across the state were doing their jobs strongly not hiding or having to hide in an enclosed bunker. My advice for him is stay there and don't leave until Biden takes over instead. I support US Presidents 'that don't hide in bunkers'. [paraphrasing jackass 2016 critical comments about McCain's Vietnam service experience].
The antifa reference is since there is no such organization that actually exists, any US citizen that protests, disagrees, or is one of the various groups that are hated [non-white, Democratic [ranging from liberal or socialist to centric], artists, college educated, scientists, journalists, lawyers, environmentalists etc] could be labeled as an antifa member and done away with. It is the fascists playbook. And the irony is US WWII vets or French resistance fighters that fought in WWII would be labeled antifa radicals as well....including the fictional Captain America superhero.
