No--not anti-establishment; unless you have a particular "establishment in mind? Your list of favourites include NONE of mine, for instance; I can listen to some of them, and find them "o.k., I guess", but without feeling particularly moved by them. It's all a matter of taste and/or opinion [ or, on occasion, snobbery]. People are entitled to form opinions, but only if they have given all options a "fair hearing". A matter of taste from then on. I am aware that your list of entertainers have generally a wide following. My wife certainly shares many of your tastes in music, I know.
