I don't understand the mental gymnastics that sees filtering out propaganda as "biased".
I see it actually as the opposite, as removing an intentional bias, as removing an intentional manipulation by the propaganda agent himself.
Compare to spam-filtering in your email: when you remove the noise, you get a better signal/noise ratio. When you hide information under a pile of noise you are actually "biasing".
There is no such thing as political-neutral information.
And if you believe that you alone, as an individual, have all the resources to efficiently filter out political manipulation in the information you receive then you're probably very close to the QAnon bunch.
