There's no clear answer as far as I'm concerned as to what diamat is. On a related note it seems basically useless when it comes to actually doing shit, because all it's used for is retelling stuff that happened with a marxist point of view. Then you got marxists coming up like history teachers being all like 'you gotta learn from the past to move forward in the present'. There's more but I'm not in the best of places for this right now. Maybe when I get home.
