I absolutely firmly disagree with your second paragraph but your first is absolutely correct.
What I interpreted from you was absolving him of his responsibility to walk away. It doesn’t mean we throw away the key or we don’t try to resolve the other causes, it means we also work to create a society that encourages walking away from content that radicalizes people to violence and hate. That we create alternatives for them. That we establish the understanding that one behavior is the right thing to do in a situation. We do this in addition to breaking apart the alt right pipeline because we need to develop more societal resilience to hate sellers.
I apologize for misinterpreting you initially.
I don’t want him in prison for the sake of punishment, but to keep society safe from him until rehabilitation can happen. And I’m going to continue fighting to reform prison so it actually attempts to use evidence based rehabilitation instead of just hurting people stuck in cages.
Now frankly I’m done here because it’s late and I really don’t like accusatory arguing for several paragraphs over moral responsibility with strangers on the internet.
