In fact, class warfare is precisely the mass of the population fighting against the elite tyrants, i.e. workers against capitalists in Marxist terms.
That's always the official story. In practice, an environment of constant fear and distrust is created as the instigators use class warfare to set the population against itself, throwing the country into chaos, giving the instigators more favorable odds for their coup against the existing elite.
You appear to be using some strange American interpretation of the term "class warfare".
No, he's just saying it like it is. Here's a shot in the dark: maybe he knows about the post-war "liberation" of China, where [Peasant A], who owned one cooking pot, would accuse his neighbor [Peasant B], who owned TWO cooking pots ("oh, such a DECADENT CAPITALIST!!"), of being a "landlord". The "landlord" was then tortured and executed. If [Peasant B] got wind of it and chose to lamb it, any family he left behind would be tortured and executed instead. Communist Russia went through a similar phase with their "kulaks". In either country, it was a fantastic way for one person to sic a lynch mob on anyone they wanted, and show their class warfare cred in the process.
