Nothing crazy, just a clip of a German version of the Unite The Right rally, some AFD rallies and some other right wing things that were relevant at the time and Hitler saying "now this, this I can work with"
Some people got big mad and allegedly it inspired this sketch though I don't think they're related
That reminds of when Strange New Worlds presented the bad times before United Earth and the Federation by showing the Jan 6 chud riot. The MAGAts malded sooooo hard.
