From a reader (I haven’t looked into the Clear Channel stuff, btw):

For What It’s Worth
By going to concerts by imbecile leftie musicians and buying their
music you validate their world view, and, coincidentally, provide them
with the wherewithal to fund imbecile leftie politicians.

There was a loud outcry when some DJs signed on to a “Boycott the Dixie
Chicks” movement. Quite a few writers boldly proclaimed that Clear
Channel Communications owners were fascists and etc.
But Clear Channel Communications owners never called for a Dixie Chicks
boycott, neither did Clear Channel management. In fact, Clear Channel
Communications were the promoters of the Dixie Chicks Tour.
Conspiracy theorists might offer the thought that the whole “boycott”
was a PR gimmick for the Chicks Tour.
