Well sports news is entertainment. There are specialised sports reporters and sports segments. Sports fans don't usually burn down city blocks when their team loses. Maybe identity politics outrage news is also serving a market demand. However it should be clear if the news is not proactive and tethered to underlying reality, i.e. if police are not actually racist as portrayed by CNN then the net social effect of such fake news is clearly negative. I don't think there is a such thing as fake sports news. There is clearly fake business news. When the media promotes ideas like ubiquitous AI and self driving cars it leads to malinvestment.
