You cannot simply give me one criterion, one that's conveniently specific to RT, to validate the statement in parent.

Both sides are, generally speaking, enforcing a narrative and rejecting objectivity in favor of the narrative ergo it's propaganda

It's the only criterion that matters when that country started a war. It's not specific to RT, it's specific to all media still able to publish and air in Russia.

Freedom of press for me but not for thee.

Any war the US started had significant opposition in local media. Saying that it's the same is disingenuous at best, Russian propaganda at worst.
