You have to separate the violence from the problem. I know many people who have had their lives destroyed and who have been violent because of alcoholism. That doesn’t mean that putting them in a cage or stealing from them is the solution. To the contrary it is often an enabler and amplifier.
I’m sorry you have had a terrible experience, but your categorization of me or my “lack of experience” might suggest you aren’t considering a real solution and only projecting an anger about it onto others.
One does not have to have cancer in order to understand or be knowledgeable about what does or does not work in treating it.
