Signal is moderation.
Generating signal is moderating noise. The first moderator of any message is the person converting ideas into language. Understanding the interplay of how messages get moderated by the various layers they pass through is what media literacy is.
Sorry, were you around for the past several elections? Perhaps the 2020 elections where, upon the progressives banding with Biden to get him elected with the expectation that we would be able to “push him to the left”, the Democratic party decided that the reason they didn’t win more seats was because Progressives had damaged their chances of winning, and they must be marginalized. Or perhaps the 2016 elections where, the target of a long running hate campaign was preferred by the party over the popular progressive candidate who was then blamed for his supporters not being won over. Or the 2012 elections where the incumbent Democrat failed to deliver on progressive policies and was a high water mark for drone strikes, but progressives helped bring the win over the candidate Republicans weren’t excited for.
I voted for Harris in hopes that she’d beat out Trump despite how much she and Biden before her discarded progressive policy. I was under no expectation of Progressives being able to do a damn thing to reach her.
