Making any kind of judgment about what’s “important” or “worthy” is exactly what OP was saying - that media suffer from bias and rarely confine themselves to neutral reporting of facts.
I don't know how this fiction has to be represented in every discussion. I don't want neutral unbiased reporting if it requires giving equal time to people who think that neutral unbiased reporting is real. The selection of what's important to report is literal biasing.
You're right, determining what's newsworthy is a biased process in and of itself. But that doesn't mean throwing the baby out with the bathwater, neutrality is still something we should constantly aim for, even if it's a moving target.
For example, if a media outlet compare actual vs expected turnout for a Trump rally and report that turnout was "lower than expected", it would be plainly biased not to do the same comparison for Biden. The lines are obviously going to blur at some point (where 'balance' involves publishing something far less 'newsworthy'), but it's a lot like the definition of pornography - you know it when you see it.
Besides, most modern media outlets are blatantly pushing their own narratives anyway - I'd say it's far more important that we fix this before moving on to the smaller problem of selection bias.
