Protest songs aren't about stylistic niceties. They're about capturing the moment. You might as well ask the Wobblies to include a stanza in their songs about how the capitalist factory-owners are all really nice guys at heart.

Neil Young isn't the best tunesmith (or wordsmith) (or singer), but he captured the moment like nobody else did. That's why his song endures.

but that's my penguin state-of-mind.
