Nobody among the intellectual class anticipated Trump's election in 2016. Much like physicists hypothesized dark matter to account for the apparent greater mass necessary to stabilize galaxies and such, the political intelligentsia hypothesized an enormous, hidden body of "dark Nazis" to account for their chosen candidate not winning the election. It is unfathomable to them that enough people in the center, center-right, and right could be discontent enough with being told whom to vote for and why someone running on a platform of tighter immigration controls and more jobs for Americans is evil incarnate, that they were willing to "hold their nose and vote for Trump", to swing the election in his favor.
Political intellectuals tend to lean left, and whenever a rightist scores a major political victory they start predicting stormtroopers goosestepping through American streets Real Soon Now, going back to at least Reagan. So the Nazi Revival is generally accepted as real, and if you contest the idea's truth you may be considered one of them.
