Tinfoil time, but a left-wing revolt is - as we're seeing now - largely supported by the current powers that be. Banks, corporations, media types, deep-state glowies, etc. would all rather the American people be atheistic mixed-race 70-IQ consoomer dullards. None of that pesky intelligence, ethnic pride, patriotism, or personal dignity to get in the way of you buying whatever child-slave assembled shit they put in your face next.
A right-wing revolt would probably be led by a very reasonable man driven to the unreasonable, thus would be infinitely more dangerous to them. You probably know how it feels. You try all your life to live and let live and then you're blindsided by assaults on your character. You try to plead your case but your attackers won't hear it. You get dejected and perhaps feel guilt, then guilt turns into resentment, resentment into anger, anger into hate, and so on until its logical conclusion. Fast forward to post right-wing revolt and you're now in a position to make those who assaulted you hurt, would you really show them any mercy? I know I wouldn't if I were in that scenario and they know that, so the fear on the left and spineless corporate America of a right-wing revolt is visceral.
All it took for Uncle A was a rejection from a prominent art school, watching a once proud culture degenerating into filth right before his eyes and look at what he accomplished. The vested powers never want that to happen again.
