As has appeared a bit on this site, a lot of the reactionary response to the murder has been extremely banal misogyny and other petty social grievances that I think some of these people don’t understand does not merit taking someone’s life over even if we imagined they were true. It’s an extremely alienated response, that the person on the screen isn’t a real person but just kind of an idea if not a stand-in for people in your own life that you resent, so literally killing them is therefore good.
