Typical Lib. So worried about slavery from the past, but what is he doing about the 27,000,000 slaves in the world today? Nothing, they don’t matter according to his political world view.

Bob Dylan was and is a very atypical lib. Certainly he wasn't anything like what the radicals of the 1960s wanted him to be, and even expressed a sneaking admiration for Barry Goldwater. He doesn't have much enthusiasm for Obama, either, to judge by the other quote taken from the interview:
When asked if President Barack Obama was helping to shift a change, Dylan says: "I don't have any opinion on that. You have to change your heart if you want to change."
It's not like saying slavery was bad is controversial. And it's not like Dylan was explicitly giving contemporary forms of slavery approval or a pass. A reporter was angling for a quote to make his interview sell and be memorable. Dylan couldn't help obliging him. He's got a lot stirring in his brain and you can never tell what will come out on any particular occasion.
Then the quote is taken out of context and used to stir up fake controversies, before people have had a chance to actually read the whole interview. I get the feeling there's a lot less here than meets the eye, though that's true of most of these celebrity stories.
