So what you're really saying is...If Trump isn't EXACTLY like Hitler, then he's nothing like Hitler at all.

Just because Godwin's Law has a name, doesn't mean its a law at all. Fascism has appeared multiple times since its "official" creation by Mussolini almost a century ago. Besides Italy, Spain and Germany, there have been other fascist regimes in many other countries in Latin America, Asia and Europe, and innumerable fascist movements in many others. Look at Russia, Turkey, and the Philippines today. Every one of those states and regimes was different, and reflected the history, local conditions, national character and leader's personality involved. They were all different, but they shared certain characteristics in common.

Only Hitler gassed the Jews and invaded Poland, but that doesn't mean he was the only one who was a fascist, and that if you don't invade your neighbors or conduct genocide you aren't one.

There's no way I'm going to change your mind, you apparently have too much invested in making excuses for this grotesque homunculus, but I suggest you read Browning's essay carefully, he certainly anticipates and even addresses your essayist's objections. Like Mark Twain reminds us; "History may not repeat itself, but sometimes it rhymes."

History and politics are not physics, there is no absolute truth that can be specified by means of some logical proof, observation, experiment or determined by mathematical calculation. But I'm not the only person who sees the parallels between American and German fascism, almost a century apart. Maybe you can't see it, and maybe I can't convince you otherwise, but you might profit by thinking long and hard on why so many others do.
