Folks don't know but even at the time when death wish 2 and 3 came out folks were calling it out for the racist undertones.
Hell the movie falling down was another movie with racist undertones. But wasn't over the top with violence like death wish.
Also it is quite wierd how violence and death at an even more gory rate is accepted today with movies and tv shows. Folks can talk about how rape scenes in old movies can't be shown today like in the 80s.
But you can literally show on network tv today folks getting shot in the head (which you couldn't show in the past). And lets not even get into the over the top violence on cable tv shows and how these shows are played on constant loops all hours of the day throughout the week.
