It starts at the home. Shitbag parents that don't raise their kids create this. Cars aren't responsible for car wrecks, forks aren't responsible for making people fat! I've never seen a gun walk itself into a bank and rob it? It's a people problem. People need to learn to deal with stress, anxiety, depression etc. Everybody has it. It's how you deal with it that makes the difference. Being hopped up on medication isn't the answer.
I get your point that bad parenting can contribute to bad actions by young people, but there are a lot of excellent parents who have been subject to tragedies that had nothing to do with the quality of parenting. I completely agree with those who have pointed out this fact in response to your post. Over simplification is the domain of the internet and social media, and this site is a social media site.
That said, I've never watched or listened to Charlie Kirk. I had to ask who he was, and then was reminded he was giving Mike Lee some cover during the public debates this summer. As much as I disagree with Mike Lee, the fact that anyones life is in danger for having opposing opinions should concern all of us, and it is a good thing that so many here are expressing this concern.
I have some people who I know I disagree with, yet I intentionally meet them for coffee or lunch, as they force my mind to think about things that would not happen in my daily echo chamber. I look forward to these meetings, as every single time I have had my views challenged, which has made me more interested in where my own biases originate.
I am very concerned that we have reached a point where expression of opposite views endangers people's lives, their health, their families, and their careers. Are we really that weak and insecure that we cannot accept opposing views and try to understand those perspectives? Are we so fragile that we view opposing views as threatening? Do we need to be "protected" from any words or ideas that might be different than our own?
In the last year I've listened to a really interesting book by Jonathan Haidt,
Coddling of the American Mind. In that book, he almost explains how people who have been coddled and protected, to the point that they struggle to cope with environments where opposing thoughts are expressed. He examines that "cancel culture" on US campuses from 2015-2018. He goes into deep discussion as to how academia, which he is a part of, has failed the concept of free speech by protesting/blacklisting any speakers on campuses who have viewpoints that might be "offensive." Now, offensive is considered "harmful" rather than thought provoking.
Very sad to see this. My prayers go to his family and those who were close to him.
