They have way less state-invested authority for sure. Not no authority (their buddies in police forces frequently let them get away with or condone shit like the intimidation and violence which the proud boys frequently engage in). The could develop into full blown deputized brown shirts pretty easily and quickly. But most branches of law enforcement in the u.s. and Canada already have secret police, and given the key part that police have played and are playing in the current fascist upsurge, I doubt they would require or allow the Proud Boys to encroach on their turf by becoming like the Gestapo.
