.. but this seems a little agent provocateurish to me.
Exactly. This person is highly likely an operative.
One role of an operative is to control a target (i.e. truth or movement) and derail it. They are typically successful by making the target so distasteful to the mainstream that it will not be listened to by the mainstream, not matter what the substance. Many times, they frame targets as "conspiracies" or "conspiracy theories," which possess highly negative connotations in mainstream audiences and therefore are inherently distasteful.
Here, this person is attempting to derail substance by wearing a balaclava, disguising his voice, and calling himself an "anti-terrorist." All of these actions are powerful psychological statements that would most certainly turn away any individual who considers themselves mainstream. And these mainstream individuals, once turned away from the messenger, also turn away from the message, making it more difficult to address the pertinent substance within the message.
If the argument is credible, then there is no reason to deliver it in this manner - wearing a balaclava and under the terrorism label. Free speech is an inalienable right, and discussions of these sorts can certainly take place in a reasonable and responsible manner.
So, while to some, this youtuber appears to be fighting a good fight, he is actually discrediting the message and creating rationale for stifling such discussion in the future. This is all by design, the technique has been used for centuries, and alert individuals should be aware of it and guard against it.
On Edit: Upon listening to this video again, it seems to me that this video is designed to produce chatter on the internet about "sedition." Here's a tip, he specifically said to communicate via the internet. Why not suggest by word of mouth, and ground mail? If he's so smart, why advise people to use a medium he knows is transparent?
This guy is setting a trap. First, he wants people to start discussing violent and perhaps illegal actions, then use the internet to do it, where those individuals can be tracked.
We do not need illegal activities in order to regain our Constitution and the rule of law. And no responsible caring citizen would suggest such action. This is not the course to follow, and people like him should be dismissed as provocateurs.
