Agreed on all points.I don't necessarily want to dive into a debate; however, I am not sure what Marcus said was the controversial?
Matt gets to keep his mask on and his identity secret so the fact that he was charged with manslaughter does really affect Matt Murdock, just "Daredevil". The moment he walks out of prison and takes his mask off his "normal" life is not affected one bit. For Marcus, he doesn't have that luxury.
Also, Matt got 2 years for pleading guilty to manslaughter whereas Marcus got 3 years for drug possession. Marcus is also a person of color. It is really not debatable that there is inequity in the US criminal justice system particularly when it comes to the war on drugs, minorities, socio-economic status and the sentencing that goes along with it. Add to the fact that Matt had one of, if not the best lawyer in NYC defending him in Foggy Nelson (and Kirsten being an exceptional attorney as well); whereas, Macrus likely had a public defender. I also understand why Marcus thinks that Matt will get out early because of who he is.
Last thing I will say is that comics have always been a place for social/political commentary so this kind of thing really isn't anything new; Claremont's X-Men (particularly God Loves, Man Kills), Watchmen, V for Vendetta, early Iron Man, Nocenti's Daredevil run just to name a few. And while I don't necessarily like when it is shoehorned into the story (like it was at time during Nocenti's run), when it fits the story it can create a powerful narrative. And I think here it very much fits. In Matt's mind him going to prison and serving the sentence is paying for the crime he committed, what this interaction shows is that he may not be paying for it as much as he thinks. Also, Matt is a lawyer, spending much of his career as a defense attorney, I think this could be a good experience for him to further understand the inequities in the world and fight to improve it both as Daredevil and Matt Murdock the lawyer.
