>So why not make fun of them? There's no downside.
...except the populist right backlash, triggered in part by their resentment at coastal "elites" (think yuppies, not people who fly to davos annually) sneering at them.
They will do that anyway. No amount of pandering will change their minds.
The "coastal elites" they resent are made up by conservative media. No behavior changes by the yuppies can affect the ever-increasing resentment people feel in response to this sneering bully, because the bully is made up and the tendency of RW media to use ever-more-dire portrayals of supposed societal ills.
As an aside, I think the culture which produces this result is related to people in the US always thinking crime is increasing, regardless of actual crime trends.
