What part of the message was cryptic? I thought it was pretty clear. He was drawing parallels between the political climate in the US and in Germany leading up to the Nazi era; while he invokes Godwin's Law, it's certainly true that a post-WWI German populace elected populists like Hitler to "make Germany great again." He is also lamenting support for this alt-rightist (as we call it today) populism among the anarchist community because many of its tenets violate anarchist principles.

Thank u @nocturnal for making it clear for me. Appreciate it :)
