What Is The Songwriter?

My Q 4 2day:  Does a songwriter have a responsibility to create expressly political work?  Is the ideal songwriter a poet, a polemicist or simply a creator who uniquely sets their own feelings to endearing music?
Some say Phil Ochs was right to stick to his political guns and Bob Dylan was wrong for not sticking to his.  Some would say Bruce Spingsteen was right to grind axes, while others would say they prefer his introspective stuff.  Some would tell me to add more to my political repertoire.  Others prefer my love songs or pop.
I like recently-deceased folk songwriter Jack Hardy:  he did everything, did it well and apologized for nothing.  He was, like Dylan, both political and romantic.  He obviously did not create out of any major sense of responsibility or preference.  He just created based upon his desire to express feelings, political or personal.  That's closest to my attitude.  I am bothered by people who suggest a writer is not carrying out their responsibility or destiny because they don't adhere unceasingly to one line or the other.  I like Bob Dylan and Jack Hardy:  be an unrepentant creator and do what you prefer to do.  It will best express your feelings.
