This is just my personal opinion, feel free to disregard it.
I have had many friends get involved in all sorts of weird things, from Landmark, to Amway, to various cults, sects, groups, etc.
I have never tried to "save" any of them.
What i have done is given people the "facts" as were known to me.
I have emailed people info that the organization they are involved in might be a "cult" from an anonymous email address... (that sorta worked)...
You might notify his folks of what he is doing, but if the guy is 33 years old....
My approach now is to first realize i cannot "save" anyone from themselves. That might seem insensitive, but there is some truth to that.
But i would communicate with someone in a reasonable way, and try to present the opposing ideas to them.
But in my experience, it doesn't work very well.
The people who i knew who went Landmarkian just left the circle of people i know.
Just my opinion.
