They do if they are writers. More silliness.
Only sleazy writers. Moral writers, regardless of the subject, write for the greater glory of God.
The "he's an artist" defense doesn't go very far.
His artistic "struggles with demons" are fair to examine. In Webb's case it fits a pattern that is very damaging to him politically.
Everyone who meets Webb, like you, seems to find him weird. "Wrapped too tight" seems to be the common impression.
(Though such a perverse personality may actually be a benefit to an artist.)
