Blaming those ground under the heel of the US Justice system for being forcibly made into "parasites" is almost as repugnant as encouraging our youth to side with the oppressors instead of the oppressed
The writing off mass injustice and suffering as 'semantics' notwithstanding, you might enjoy learning that 'parasite' described those in Greek and Roman society who earned their daily meals by entertaining and flattering at the dinner tables of the rich
Hopefully you appreciate the irony in the word now describing those forced to live in incarceration, to satisfy a societal elite with a fetish for moralizing and punishment
