Why is criticism reserved only for the one that did not start the current war?

Probably because none of us live in Russia, so criticizing them is a waste of time. Of course they suck, but there's nothing we can do about it. Nobody in Russia is ever going to read our criticism.

We do, however, mostly live in NATO-aligned countries. We CAN affect change in our own countries. That is a productive conversation to have.

Can you show in what way is Ukraine more right-wing than Russia?

Nobody is claiming that. You're having an argument with a guy you made up.
