Almost the entire American right wing media is continually hate- and fearmongering about their perceived political opponents, actively and/or knowingly spreading disinformation, and has been for my entire adult life, at least as long as I've been paying attention, which is going on several decades. That's their only move, give people enemies so they don't actually have to propose solutions to anything. It's easy to give people enemies, much harder to actually solve complicated problems that require getting everyone on board. There used to be a more intellectual, reality-focused American right wing (and still is, but to a vastly smaller degree than just a few years ago). But now Alex Jones has replaced William F. Buckley and modern Republicans are much more likely to know about Rush Limbaugh than Edmund Burke. Buckley and Burke would get tarred and feathered as RINOs nowadays and that's really saying something.
That's not an opinion or a judgement, that's just reality, as much as 1+1=2 or the sky being blue. It doesn't require interpreting anything or contextualizing anything. It's obvious and plain as day, and eyes and ears and integrity and maturity are all that are required to perceive it. I absolutely believe beyond a shadow of a doubt that any reasonable application of any reasonable rules of moderation concerning threats, abuse, and misinformation would have much more impact on a typical Trump supporter in 2020 than anyone else (still faithful in 2020 folks, that's the type of person we're talking about here), and that that would be almost certainly the fault of the individual, and not biased moderation. The only way moderation would affect both sides equally would be if both sides were the same, or composed of the same sort of people.
But both sides have never been the same, and that's more true now than at any time since the Civil War. Except that now Republicans identify with Confederates instead of Lincoln and his ideals, and somehow Democrats flipped from representing Evangelical rural Southerners to representing the industrialized, urban, and successful parts of America, that were represented by Republicans in Lincoln's day.
FWIW I agree with George Washington that political parties themselves are the poison pill that repeatedly divides and screws up America, and that our current system is fatally flawed because it naturally leads to a two-party system, and that two-party systems by definition lead to more corruption and shittier governance. Just because one party is clearly criminally corrupt doesn't make the other party the goodguys, but until (if ever) we get rid of FPTP voting, it's a "pick the lesser evil" situation, and hoo boy is one evil obviously lesser than the other one.
