The thing that I find reprehensible artistically is that, as an artist, it's your job to inspire thought, and when you choose to limit what you say, you choose to limit your expressiveness. I think that it undercuts the ability to create art. It's like deciding to be an author but refusing to use the letters 'F', 'M', and 'Q'.
I don't look upon it as limiting his expressiveness.
As any writing instructor will tell you, "Write about what you know."
Jeff's songwriting comes from his heart, and is about a subject he knows and loves. I'm guessing he has more to say than he could express in a lifetime, so why should he change his course in order to satisfy somebody else's ideas about artistic integrity?
I don't want to "put words in his mouth" but I am guessing that Jeff's music is done more for his own (very) personal satisfaction than it is for the entertainment/education/?? of others.
Now THAT speaks to me of artistic integrity.
