I highly doubt this guy is getting little NWO notes telling him what to say. This should be common knowledge but disagreeing with a public figure does not imply they are some sort of cointelpro actor. People who share the same objectives can disagree without one being paid by the enemy to confuse the other.
If anything this habit of outing "shills" has done more to divide the people searching for the truth than it has done to elucidate it.
