Loyalty Day was a non-event, obscure and unknown by most. But under Trump it takes on a more sinister implication because his most ardent fans are fueled by hate. They're the weasely informant types, who, if given the power to rat out disloyal citizens, would do so in a heartbeat. They're the types who are so weak that they greatly desire a strongman to right the world for them. In other words, they're dangerous fucking goons who would take a loyalty oath for Trump.
I don't want to admit that I'm still in shock that so many Americans could be so authoritarian, but I am.
