There are two major reasons for the change you have noted.
One thing is, our country has drifted way to the right - this includes moderates, but particularly applies to those who are currently considered to be part of the far right. Most of the damage began during the Reagan administration and continues to this day.
This web site does a good job of making this point. The average person in this country has gotten just plain meaner, but you know that's not a separate point if you understand what today's right wingers want.
You might remember this from a couple of years ago:
Casino gives Ronstadt the boot
Singer sparked near-riot by praising Moore’s filmLAS VEGAS - Singer Linda Ronstadt not only got booed, she got the boot after praising filmmaker Michael Moore and his new movie "Fahrenheit 9/11" during a performance.
Before singing "Desperado" for an encore Saturday night, Ronstadt called Moore a "great American patriot" and "someone who is spreading the truth." She also encouraged the audience at the Aladdin hotel-casino to see the documentary about President Bush.
Ronstadt’s comments drew loud boos, and some of the 4,500 people in attendance stormed out of the theater. People also tore down concert posters and tossed cocktails into the air.
http://www.msnbc.msn.com/id/5462483 Evidence of my first point, you might think. But it really didn't happen that way.
My wife & I were at the Linda Ronstadt performance in question, at the Aladdin in Las Vegas, and quite frankly, Aladdin President Bill Timmins' account of what happened is complete crap. There was mixed booing and cheering at Ronstadt's pro-Michael Moore comment, and that was about the extent of the "bedlam" that supposedly broke out. I saw no posters being torn down or cocktails being thrown in the air, and if people stomped out of the theatre unhappy, it was because 1) that was the last song Ronstadt performed; it was her encore; and 2) she mainly sang her standards repertoire, with the Nelson Riddle orchestrations, and a large part of the crowd wanted to hear more of her rock-'n'-roll stuff; she got the biggest round of applause for doing a lackadaisical run-through of her version of "Blue Bayou."
Frankly, my suspicion is that Timmins is way overdramatizing what happened, in order to justify giving Ronstadt the boot. It simply wasn't that big a deal.
