I actually support the side which is magnitudes less violent. And there is a difference between killing fascists like the Soviets did and killing anti-colonial freedom fighters but mostly civilians like the colonial powers did.

You can only oppose everyone if your opposition doesn’t actually do anything. If you’re actually affecting things your opposition of one will strengthen the other. You have to be against the US empire and for multipolarity or against multipolarity and for the US empire. There isn’t a third option.
