The neocon/neolib establishment supports Ukraine so some of that bled into right-wing circles, who then care about this by-proxy or act like they do. On the other hand almost nobody supports Russia unless they are Russian. (or edgy ethnat anons who fell for Putin's white savior psyop) You might find more pro-Russian propaganda on actual communist forums. Not because Russia is communist, but their traditional allies are communist regimes and people in those circles have obligatory support of Russia the way patriotic Americans must support Ukraine for some reason.

I bet there's lots of propaganda on T_D if you sort new, just due to the sheer volume of handshake posts.
