I don't either. And what I am about to say is a general observation from what I have seen from the left's reactions to a couple of recent events. If they don't reflect your views, then great.
The people who are celebrating the CEO's murder and are making the killer out to be a hero, are from the left. So those are some people who probably see it as a left vs right thing. But not everyone on the left is doing that.
At the same time, many on the left have been outraged over Daniel Penny being found not guilty in his trial over the death Jordan Neely. They view the CEO's death to be, in a way, justified. But in no way do they view Neely's death to be justified. And AOC is one of the people who I am speaking of, so it's not just media click baiters or lunatics on Reddit. It goes as deep as elected politicians.
