So from having had a few exchanges with pro Russian accounts on Lemmy (which seems to be infested with a few very active ones) this is a summary of their arguments:

• "Ukraine is Nazi"
• "Well far right parties got a total of under 6% of the vote, and they elected a Jewish man president"
• "yeah but Bandera and whatabout America"

• "Ukraine killed ethnic Russians"
• "A huge percentage of their population are ethnic Russians, including in government, and they are fine, and were until the Russian invasion. And now it's Russia that has killed, maimed and raped more ethnic Russians, including civilians, than Ukraine every did or even could. Including their own people thorough incompetence and corruption".
• "Yeah but Bandera, and whatabout America"

• "Ukraine is fighting because they are forced to by their colonial masters, the USA and NATO, and Ukrainians will keep dying so long as they keep being armed"
• "Actually > 90% of the population wants to continue fighting for their country back, so what you're basically saying is you think Ukrainians should be abandoned to Russian enslavement"
• "Yeah but Bandera, and whatabout America"

• "NATO and USA are colonialists and this is just more colonialism"
• "Actually both Russia and China are actual, bone fide land empires, with ethnic minorities that are forced to live like colonized people - including doing the fighting for Russia while their families back home live in misery and squalor and Putin's Mafia collect mansions, private jets and yachts"
• "Yeah but Bandera, and whatabout America"
