I like the approach of Garrison Keillor, albeit one he proposed in 2016.
America has a lot of inertia and it is difficult to move it in a completely new direction. We've survived plenty over the years, and while there are some scary MAGA proponents, I don't really believe that most voted for Trump due to brainwashing. Like has been happening since our inception, some people just need to be dragged into the future kicking and screaming, but each generation is better than the past. Just since my time on this site we've already dragged forward enough people to accept gay marriage that I don't ever see us 'making America great again' to the point where anyone makes a serious attempt to outlaw it. We'll be fine, IMHO.
