Your point is best made by history — It took years to get FDRs Fascism stopped ...
There's more to history than FDR. In that particular instance, certainly time healed many wounds.
Mark Twain once said, "The past does not repeat itself, but it rhymes."
We've seen courts move too slowly or find themselves too weak to stop the loss of freedom before. We've seen courts slowly undo the damage that tyrants have sought to impose on the law.
How will this scenario rhyme with the past? You have great hope that we have enough time left, or the courts have enough power left, to stop what is unfolding. That is one rhyme that could come to pass. But at this stage, I find it increasingly less likely.
