I don't agree with a lot of the things Charlie Kirk said, and as someone who is not an American, there was also a lot of things he said I simply didn't care about because they didn't apply to me. I also found that his way of communicating was more geared towards encouraging discussions that would generate views. But despite all that, I can appreciate that he was a man who was willing to have a (mostly) civil conversation with all sides, something I wish more people would try to do.
American politics isn't politics, it's one step short of being like football hooliganism for supposedly smart people.
And the news networks eat that shit up. They love a boogeyman, because it's good for ratings.
You could imagine a different algorithm that promoted peaceful, thoughtful interactions. But that would have led to the death of Facebook, twitter, news networks, etc.
We may in fact be here due to sheer greed. The media companies have profited by creating discontent in our society rather than content.
