I am not making a statement on the message in the video, in fact I haven't really watched the video all the way through.
But we're conspiracy theorists right? Anyway the video was produced by James Howerton https://twitter.com/jason_howerton
He was a producer on the blaze tv and now is a wealthy conservative online media producer. As much as I hate the majority report on YouTube, they do look into this a little. https://www.youtube.com/watch?v=4TDTYf8tvwU
Whats my point? I don't really have one other than to say that this video and the popularity isn't really a result of organic activity. The video was planned, produced, and orchestrated, and comes off as right-wing astroturfing.
He could very well be a plant, but it's not only the "bad guys" that can do plants.
Even if this WAS planned, what are the net effects of his deployment? So far, it seems to be shining a light on the fact that we are not as different and divided as they want us to be (see all the "reaction" videos).
That song is speaking to (and awakening) a long-slumbering piece of the souls of many Americans, many of them people who, before, did not even realize they are slaves to a system.
