It differs a lot from what online places like Reddit would have you believe.
The assassination happened while I was at work on break, and when I came back everyone had found out about it and was talking about it. People don't really talk politics much at all at work, other than the typical "haha both candidates suck am I right" type shit. But for some reason the topic had come up. So many of my coworkers are just normie centrist/apolitical older zoomers and millenials who didn't agree with a lot of what Charlie stood for. But they were all horrified and couldn't stop talking about how awful it is to kill someone just for disagreeing with them.
Basically, my point is, Reddit and the online left are unbelievably astroturfed in order to present an idea to niggercattle that this is what the average person believes, so you should believe it too. Going against that narrative is BAD, and you're a BAD person, and BAD people aren't even worthy of life. If you went on there you'd think everyone except republicans are celebrating his death. But that doesn't represent at all what most average normies actually believe, even younger ones. Even the normie liberals aren't actually in favor of the extremist shit that online progressives act like everyone agrees with.
About 5 years ago, I feel like everyone would have been laughing about his death. There's definitely been a shift in the public consciousness. Even people who went along with the local they/them's pronouns as to not get fired have stopped caring as much and have just been calling her a she when she's not there, and no one else gives a fuck. We were even talking about the murder of that Ukranian girl too, and everyone was agreeing that the killer should be put down. People have had enough, and it just shows how so much of this stuff in the past was just going along with it to not rock the boat, and not what most people actually believed. The progressive narrative just isn't landing anymore.
