I think Peterdjones means that Objectivists would be good people for Loup-Vaillant to hang out with, to teach him what it feels like to be subjected to obnoxious argumentation and make him realize on a gut level that it doesn't help and causes needless unhappiness. I suspect from personal experience that it would backfire--I tend to act more like the people I hang out with, and I was a lot more obnoxious when I spent time on Pharyngula before coming here--but YMMV.

At least, that makes more sense to me than Peterdjones actually wanting Loup-Vaillant to eat Objectivists.
