I wonder how this author feels about Johnny Cash who has sung songs about:
* Shooting a man "just to watch him die" (Folsom Prison Blues)
* Doing drugs & killing his wife/lover (Cocaine Blues)
* Killing his wife/lover (Delia's Gone)
* Trying to kill his father (A Boy Named Sue)
* Breaking the law & fleeing from the authorities (Wanted Man)
* Getting ready to inflict violence on his boss (Oney)
* Dissrespect for the law (Starkville County Jail & San Quentin)
And so on.........
Rap Music (like SH#&) Happens. However, you point is valid. I'm sure every generation listens to the next gen's music and makes fun of it.
As far as old(er) fart goes, if you live long enough you'll get old and make fun of the younger, up and coming generation's clothes and music. It's a fun part of living a boring older life.
While Johnny Cash did sing of crime and criminals he did not promote the lifestyle. In fact he was a born again Christian before he started his career. He performed many more gospel songs (with his wife June Carter) than he did country songs.
While he did perform many criminal type songs it was to show that through the saving grace of God that if someone like him could be saved then so could other felons. Through gospel and country music, his music was his ministry.
* Breaking the law & fleeing from the authorities (Wanted Man)
Breaking hearts and fleeing women. You need to listen to the lyrics of Wanted Man more closely.
