Hmm..
So reasons for liking them are not suspect, whereas reasons for not liking them are.. That could come off as a bit "Inquisitional" to the casual observer..
I don't like "Sugarland" because of one live song I saw on the CMT awards that probably had bad sound.
I liked John Mayall for 30 years until I saw him in a pathetic ACL show with the had-to-be-embarrassed Blues Breakers.
I think there are many many people like me that are just looking for the slightest reason to "not like" acts or stars.
I know plenty of people that hate Jr Brown for reasons that have NOTHING to do with his music. They probably don't like his music because of it.
Some people don't and didn't like Buddy Rich, after his R Rated Rant. Some of us liked him more
In the end I think that the public's reasons for liking or not liking acts or stars often are not rooted at all in the body of their creative works.
Heck. Johnny Bond, Spade Cooley, and even Jimmy Dean had their works diminished greatly by non-musical episodes.
What's new?
Maybe an H. L. Mencken quote is appropriate..
