I think that grindy death, like grindcore and punk, musically make me think of such political lyrics. To be honest, i dont dislike such if they are well written. The idea maybe "fight the system, step on the faces of the corporate maggots", but written well. I think that such lyrics need to sound negative and pessimistic and scornful, creating the atmosphere that the lyricist finds himself supreme in his struggle against some sort of an error. Well, not quite, but anyway. Old Napalm Death lyrics are nice.
