I think a lot of it is because they are SO vested in the notion that the ENTIRE West is under the control of “Globalists”, “Soros”, etc etc and their hatred is so burning hot for it that they cannot fathom the idea of agreeing with them on the issue of Ukraine. If the choice was Hitler vs “Globalist”, its Hitler. Same for Stalin, Mao, Pol Pot, the same.
I cant remember the last time but for maybe a brief period after 9/11 that the left and most of the right agree on the Ukraine issue. Think about that...
Maybe because it is????
