Producers of slanted media could not persist unless there was a market for biased information. A large source of demand for media bias is likely to be people who protest opposing views or claim to be offended by so-called 'microaggressions.' Their intolerance for opposing views that by definition add to balanced perspective is so great that they refuse to admit those viewpoints for consideration.
Instead, the microaggression crowd will want to remain inside their comfort zone and consume media that reinforces their worldview and provides a source of positive psychic income.
