This has no connection between ideologies.
Ukraine is ruled by nazis and you're simping for them, and bending over backwards to deny reality as "Russian propaganda" (hey, who else in history liked to do that?) makes you look like an even bigger sucker. Because deep down you know you're denying the evidence of your eyes and ears, but admitting that means admitting the tankies were right, and that's intolerable, so you keep on trucking towards Nuremburg.
