I think that finally liberals are getting sick of it coming from the press, especially at outlets like the New York Times which just sold a lot of subscriptions based on an advertising campaign about fighting "alternative facts." Once upon a time people accepted the reality of bullshit
anti-abortion screeds or deceptive climate change advertorials from Exxon in the opinion section, but this is a product that you are asking people to pay for and why should they expect a kick in the face with their Sunday paper? Outlets like the Times aren't required to be any specific way. They choose to be that way.
