Sorry, but good luck with that.
A better approach would be presenting them with an undeniable proof of YHVH's existence and the outcome of inequity gone unchecked. Unfortunately most Christian religions are failing miserably in this fundamental area.
To reach them requires removing the mistranslations, inconsistences, and outright fabrications being presented as the Word of the Almighty today. People are much smarter today and better able to think for themselves.
What they really need, and are seeking, is the truth! Someone holding their hand and telling them they are really good little boys and girls and that everything will be alright, isn't going to work, and will only lead to more iniquity.
This was all was prophesied thousands of years ago and we're seeing those prophecies being fulfilled right before our eyes.
I have been reading a little about Bart Ehrman, a Scripture scholar who has been doing a lot of writing and speaking over the past 20 ore 30 years about what he would call about the "mistranslations, inconsistencies, and outright fabrication" in Scripture. This approach has resulted in his conversion from Evangelical Christianity to agnosticism, and has acted as a solvent, dissolving the faith of hundreds of students he has influenced.
I'm not sure I understand your point: how does a debunking and skeptical approach toward our received Scripture assist in people's moral guidance?
"People are much smarter today"
That I find dubious.
