The question I have is: will there be a U.S.A. as it was commonly understood to be for several centuries, or will it be a snowflake "utopia"?....which will collapse in short order.
To answer that, you have to take the snowflakes out of the freezer and stick them in the real world to see what happens.
One of my temperature gauges for the state of society is a pair of websites: notalwaysright and notalwaysworking (there are others as well) and Yelp reviews. The first is stories from retail and customer service, submitted by workers and customers who tend to the younger end of the spectrum. The second needs no introduction. Sort of self selected sampling, yes, but a bigger sample than I'd get by personal observation.
In my general opinion based on that sampling, the entitled, fearful outrage of the snowflakes doesn't survive the world for very long or at all. They get their heads filled with mush at college, then go out and work, same as we did.
So, my conclusion is America as you know it will mostly survive intact. You may disagree - the information I used is freely available for you also.
