Deepak Chopra recently put it in a clear way typical of this view:
The modern world is willing to throw out any number of beliefs about God if the facts don't fit. Science isn't willing to throw out a single piece of data, however, to satisfy an article of faith.
My job as the sociologist in this discussion was to bring in this inconvenient truth: If you ask most Americans "did God create the universe pretty much the way it is now within the last 10,000 years?" 45% say yes. The illustration I used was that every time we go to Walmart (the biggest store in our small town), assume that someone in the aisle with you is a young-earth creationist.
Deepak Chopra takes if for granted that the 45%, our fellow Americans in the Walmart aisle, are not members of the modern world. The arrogance of that assumption really ticks them off. That does not make them right - I don't think they are right. I think, though, that the reaction to that arrogance is what is really behind the political anger that we see now.
