Or maybe it's okay to call out bullshit on your own side?
America has committed a LOT of atrocities. Trail of Tears. Pine Ridge. Slavery for god's sake. Fuck, we invaded the wrong country after 9/11 and let Saudi get away with sponsoring it. Then we have the Monroe Doctrine and South America plus all the Middle Eastern governments that we overthrew. The nuking of Japan was the decision to save millions of soldiers at the expense of hundreds of thousands of innocent civilians. Fewer lives, yes, but it's rather difficult to justify the murder of the innocent. We're propping up Israel and allowing them to commit atrocities against the Palestinians. At this point, the US and Israel are the only real parties in the way of a two-state solution. Hamas could easily be taken care of without the killing of Palestinians who just want to be safe and secure.
Die-hard tankies refuse to call out anything on their own side (or the enemy of their enemies) and that's the problem OP is bringing up. If that doesn't describe you, then great, I'm not talking about you. There's no good-faith way to support modern day Russia and the invasion of Ukraine.
