Is this a chiasmus:"Degenerate filth for filthy degenerate minds."?
This (to my way of thinking) is a bit borderline but I would be inclined to accept it as an example of chiasmus.
The chiasmus structure would be better balanced as:
"Degenerate filth for filth degenerates minds."
which has (again, to my mind) a clearer repetition of structure with reversed components.
