What you call the 'endless stream of right wing media' for the last 40 years ... well first, get your history straight: it started in the 90s with Rush Limbaugh et al AM radio. Not 40 years, more like 30. If you have that basic fact wrong, I assume you're too young to have lived it and are reading it from somewhere.
Fox News started broadcasting in 1996 and really skewed right later (99?) as Right Wing radio (Limbaugh, Beck etc) identified a commercially viable audience that was completely unserved.
Limbaugh and what followed was ABSOLUTELY a reaction to the strongly left bias of the media which became evident with the election of Ronald Reagan, but really was clear during the Senate Confirmation hearing of Justice Bork. Media was always assumed to be at least slightly left (which was accepted) with a weirdo fringe of further leftism mostly around the arts. But in 1980 the Dems thought Nixon's shit had guaranteed them at least 20 years of government control and were incensed that Carter was such a milquetoast that he got humiliated by Reagan, and Mondale even worse.
Nothing makes liberals more angry than to be compelled to face the fact that they're unliked. (cf Trump 2016, Trump 2024 responses and resulting vitriol.) In the 12d after Trump took office in 2016, there were 12000 tweets threatening his life on Twitter (https://mashable.com/article/threatening-posts-secret-service). I mean you guys have tried on him twice already in the 1st 9 months.
I don't really forgive you. You guys thought you owned the world and could do whatever the fuck you wanted - bring in 3 million immigrants and then make them voters? SURE.
Biden *actually* tried to undercut democracy, we don't have to pretend-imagine 'Trump's future concentration camps' or other goofy ideas.
