Hard for me to gauge how earnest this comment is - if the media is being fair about it, you wouldn't take their coverage as evidence of extreme polarization. But maybe you are being tongue in cheek?
Well the 'mainstream media' (I now hate this term) is being pretty fair, but you have offshoot "media" companies that aren't doing any real journalism, just riling up their fanbases to get more clicks/views. The 'real' media is being fair in criticizing the social media companies for promoting Fox News / OAN / whoever else as if they're on par with actual journalism. And for sending people down rabbit holes / filter bubbles so that when they see truth they scoff at it.
