I don’t speak enough German to understand the lyrics, but Klassenhass means “Class hate” and so it’s probably about the bourgeoisie hating the working class, or proles hating on other proles when they should be in solidarity.

Not only is Vizzion a pretty good rapper, he also speaks about the class struggle openly without mincing his words. Just the imagery in the clip is enough to get any comrade teary-eyed (it features heavy use of the DDR flag o7). And it’s peak workout music, you can pop some Vizzion, imagine yourself beating up fascists, and you’re fired up for a workout.
