The words are new the idea is not. But it's a stupid idea regardless. What happens is that boomers who don't understand the internet think it's all smart people with their computers and then get cognitive dissonance when they start receiving all the death threats and unhinged nonsense that they interpret as radicalization rather than schizos.

There is some degree of crazy radicals who might actually carry stuff out, but for the most part the crazy people are out there and will find any excuse to go be crazy. In the absence of right wing propoganda they'll find left wing propoganda. In the absence of all propoganda they'll listen to the demons in their head instead.

For the most part I don't think there is much use for schizos in political activism, they can't be controlled and will just as soon make you look bad when they eventually turn on you. There's no logical reason to assume that these sorts of threats being made are deliberately engendered by those with political motivations rather than assuming they are simply the unhinged mutterings of shizos.
