It seems so easy to fall into a false balance trap. But while Western media is certainly flawed, there’s a fundamental difference between honest mistakes and intentional lies. The truth is very unlikely to be half-way between the two.
Compare: The 2016 election mispredictions were one of the most discussed topics for months in the aftermath. The Bush administration’s WMD claims are still regularly discussed, at least outside of Fox News. Journalists have in general become more skeptical of US government claims as a result ever since. That’s widely considered a good thing.
On the other hand: Russian media, as should be obvious for anyone with better memory than a proverbial goldfish, doesn’t even care how today’s message contradicts yesterday’s. The sanctions are ineffective and a grave act of war and must be stopped immediately and actually don’t work. Ukraine will never be attacked, and is actually Russian, and commits an anti-Russian genocide, and isn’t a nation, and will no longer be a nation if it doesn’t surrender immediately, and isn’t actually being attacked. It’s so inconsistent with itself that you don’t even need a second source to spot the lies.
I might feel nice and wise and balanced, but I don’t think these are circumstances where believing “both sides” is intellectually defensible.
