I am not sure that Dylan was not, at one time, a lefty...he may well have been..he was, after all, buddies with Alan Ginsberg and Lenny Bruce...
I believe his faith may have changed his world view to a large extent...His songs reflect a pro-Israel viewpoint (The Neighborhood Bully), he laments dependence on foreign oil (Slow Train Coming)..and he decries pornography in the schools (When You Gonna Wake Up)...hardly the stuff of the ACLU and the People For The American Way..
Thanks for the note about the lifted line...
I think like many of us when Dylan became a parent his life changed radically.
