if theres ever been an argument for there being an antichrist

The AntiChrist isn't an real person but it is a real idea. Demagogues come and go, often rising and falling in similar conditions and circumstances. The mythology of AntiChrist (and Christ) signals real patterns in human social behavior that generations of people have come to interpret as divine prophecy rather than intrinsic human failing.

Because the modern era grants us so much more direct and easy access to historical events, to mass communication, and to diverse perspectives, its easy to find guys like Trump scattered all through the modern historical moment. From the Park/Yoon government in S. Korea to Bolsonaro's Brazil and Modi's India and Orban's Hungary, we have reactionary, self-destructive leadership echoing through the modern political landscape. Go back a generation or two and you'll find the Reagans and Nixons, the Idi Amins and Hendrik Verwoerds, the Nicolae Ceaușescus and Fulgencio Batistas everywhere.
