I'm really sorry to hear that. That really sucks. Let's hope they can find peace since finding god didn't seem to do the trick.
I 'recycled' a friend some time ago because similar things happening. so i really know the feeling. I think as the world becomes more polarized more people will have similar experiences unfortunately.
I am also sorry to hear about your similar experience. It sucks. Seeing a many-years friendship collapse like this, is never good.
Maybe I am just angry now, and in the future I will re-consider my decision. Then again, I think I am not willing to change it if I don't see a change from the other side.
