I have some personal experience with people like Dahl. I spent 9 months in rehab/recovery. There are some people, not all, in the Twelve-Step movements who find the Christian God/Jesus as their higher power who saved them from whichever addiction they have. They generally traded one obsession for another.
In the cases of the most fervent people (like I suspect Dahl probably is), they have substituted their addiction to some substance (drugs/alcohol/sex) with an addiction to religion. This is very unfortunate for people like Coleman who have other beliefs and don't want to be a Christian. In the world of people like Dahl, Christianity has taken the place of their drug of choice (alcohol is a drug actually). One of the most annoying features of many Christian sects is the adherents are instructed to go out and convert all the other sinners and save them through Jesus. Addicts/Alcoholics are great at focusing on a goal like that. Obsessive behavior is part of addiction.
With addicts in recovery like Dahl, the owner, I have found them to be particularly obsessed with converting everyone else to see things their way. They replaced their obsession with a drug with their obsession for Christ and saving every other addict through Christ.
It can be much more harmful than helpful. They spend all their time devoting themselves to saving others through their version of redemption and don't stop to really look at the underlying issues that caused their substance abuse in the first place. They believe Jesus has lifted their burden. They used to live a drug-centered life and they simply trade that for a "Christ-centered" life.
I don't wish Dahl ill. I am certain he believes he is doing the right thing. As a "Second Chance" employer he is very much helping people with criminal records and past addiction issues find work and re-integrate into society. I think that is great. I think it will be terrible if his company goes out of business and cannot provide those jobs any longer.
I just wish people like Dahl could stop trying to make everyone else live life by their standards. This is common to Republicans, Evangelicals and people like Dahl.
