Many don’t realize that the first people Hitler sent to his concentration camps weren’t everyday Jewish citizens, but his political opponents. So, when Trump rants about retribution, locking up his opponents, and giving them “very long sentences,” I can’t help but take him seriously… because history teaches us that is what fascist dictators do during their “Day One” period to consolidate their power. (After all, if you’re hellbent on staying in power but aren’t likely to win the next election, you can’t have your political opponents running around free.) To keep fascism out of our lives, vote for democracy!
