Melodrama in the Communist Manifesto

I don't know if this is posting in the right place but I shall try again!

“The “dangerous class”, [lumpenproletariat] the social scum, that passively rotting mass thrown off by the lowest layers of the old society, may, here and there, be swept into the movement by a proletarian revolution; its conditions of life, however, prepare it far more for the part of a bribed tool of reactionary intrigue.”

This section of the Communist Manifesto I found to have elements of melodrama. It presents the argument in a very black and white manner, appeals strongly to the emotions of its audience, and dramatizes the situation. Words like “scum,” “rotting,” “lowest layers,” and “mass” are strongly evocative and bring emotion into the argument.
