See for example denmark. They have like a fucking research organization (Research-kollektivet Redox) that systematically infiltrates groups and writes long reports on them.
They fucked over the fash in Aalborg (the 4th biggest city) by infiltrating them and then destroying their spaces and outing them all. This was effective, well-planned, and well-executed.
It seems though that the American antifa acts nothing like that. From what I gather, they are totally unorganized, don't know what they're doing and who they're fighting. They also acts very impulsive, seemingly going after strangers, who are of no significance, and might not even be fascists.
I might just be ignorant, but that's the impression I'm getting. Is there any truth to it?
