I have no problems with the Indian Nations passing any laws they want, but alcoholism is not a human disease, it is a symptom of a sick society.
I know of alcoholism as my closest brother is an alcoholic. It is his choice and he is a product of his environment. He sees the inside of a bottle every day, but hasn’t seen the inside of a church in 25 years. Society tacitly approves of that lifestyle these days. And, no, you can not force or shame a drunk into detox and rehab, even if it is free.
Whether it’s a disease or not is meaningless, the problem is it’s a reality. So what do you do, just keep digging and filling holes?
