That was all there was to respond to. Come up with something, tell me all about how I downplay the harm caused by Russia.
I have said it repeatedly. You have called the invasion a "border dispute". You have attempted to excuse the invasion as a consequence of a "US backed coup" that was actually a popular protest within Ukraine that resulted in new, democratically elected leader. You have claimed that Ukraine has been killing Russian-speaking people in the Donbas, and when pressed for evidence of this you claimed they were responsible for 14,000 deaths, which I later learned was the total number of deaths - on both sides - of the war in the Donbas that was initiated by Russian separatists (and also just so happens to have been virtually identical to a dishonest claim made by Putin to excuse his invasion). You are desperate to shift the cause of the invasion, and it's moral weight, onto the USA or NATO (usually after you fail to put it onto Ukraine). You place blame ANYWHERE but at Russia, and only offer vague platitudes about Putin being bad while doing ABSOLUTELY EVERYTHING YOU CAN to remove any moral accountability or responsibility for the invasion (when you're willing to call it that) from him.
If I wanted harm done I would support supplying weapons too but like the chicken hawks in Washington you are really brave from the comfort of your armchair when it's not your life on the line. I'm for diplomacy, but that seems to be a thing of the past.
You don't care about Ukrainians, otherwise you would respect their decision to defend their home and fight off an invading force, rather than calling it a "border dispute" and constantly having to LIE about Ukraine's history.
Ukraine has the right to self defense. The USA, their military ally, has the right (and, I would argue, the moral necessity) to provide them with the means to defend themselves. Putin has the right to negotiate, but isn't willing to cease his invasion without concessions in the form of territory.
An anti-imperialist would support a powerful nation aiding a weaker nation to protect their borders from an actual invasion. That is the bare minimum principle required of being anti-imperialist. You have to REJECT IMPERIALISM and support any acts - diplomatic, hegemonic or otherwise - that curtail actual imperialism.
You wouldn't be downplaying it. You wouldn't be excusing it. You wouldn't engage in lies and repeat the ACTUAL ARGUMENTS OF AUTHORITARIAN IMPERIALISTS to support the disarming of a nation that is defending itself AGAINST imperialism
Those are things an imperialist does.
You have done them.
Hence, you're an imperialist.
