Your mistake was trying to ask for a reasonable view of Russian government's action. To the average redditoid, nothing Russia does is ever justified in any way. Fighting terrorists? "That's just an excuse to persecute minorities and national liberation!" Fighting Nazis? "Akschually Russia is real Nazis!"
Russian government been doing lot of aping from the west, and these types universally condemn it, without a hint of self reflection. If tomorrow Putin completely withdraws from Ukraine, dissolves the federation and puts pentagon in charge of the Russian military (cough south Korea), they'll still find something to blame.
