So this woman bills herself as a qualified MUSIC critic, and proceeds to shred Skynyrd's values and the "stigma" that his music implied. The politics of ad hominem at its meaningless best.
Music Nazis are gigantic bores. There is a certain amount of fun to be had criticizing music, but personal tastes are just that; personal. For the life of me, I never saw the "genius" of Prince, but he is widely recognized as a brilliant musician for some reason. Likewise, I never saw Madonna as anything other than the hype.
When people start vilifying the music, it just comes across as either snobbish or parochial. The only critique you can really trust is that of the die-hard fan. An REM fan who laments their latest release, or the Metallica fan who pines for the black album days. At least you can respect their point of view.
