I think there is a natural instinct to not believe things that are obviously propaganda, so when confronted by a party telling an obvious fantasy it’s pretty important to get the other party’s version, even if also nonsense and hope to suss out the truth.
You don't have to look very hard for the other side's version though.
Question is whether you think "Russia made a planned withdrawal from the north of the country after completing all the objectives of this military exercise which definitely isn't a war" is a more plausible description of the short-lived invasion of the north of the country than "Russia's advances have slowed down... Russia stopped advancing... Russia is retreating...". Both narratives agree that the facts on the ground are that Russian troops made large scale incursions into the north of Ukraine but aren't there any more.
Yes, most Western media has sought to emphasize Russian casualties over Ukrainian ones and Ukrainian minor success over Russian ones, but it's not like Western media hasn't been free to predict Russia will have full control of Mariupol in a couple of days for over a month now and talk up the Russian convoy advancing on Kyiv which never made it there, or like the official Russian narrative isn't palpably absurd.
