I can't even tell if this is posted in earnest, or satire, or some sort of highly advanced shitpost I am failing to grasp the nature of.

This is a classic Russian perspective on the war - that Ukraine is a gang of neo-Nazis that are dead set on eliminating Russian speakers from Ukraine by force. Russians will further claim that this gang of Russophobic neo-Nazis is led by Zelenskyy, a Jewish man who speaks Russian as his mother tongue and Ukrainian as a second language.

The absurdity of this claim should be self evident.
