I see all your points, girls. But, when a person it’s so focused on a topic, a belief, a matter up to the point that she changes her behaviour or renounces to enjoy or stay present in the other fields of her life, there’s a problem. Not only for the ones around her but also for herself.

I was wondering if she could have been brainwashed.
It happened to many young adults who were brainwashed by the Daesh.
This is very dangerous and very hard to get rid of it unless a trained professional helps her.

You can have even a radical belief but put your friends apart and have less care towards your dear son and husband.

I’d like to ask to @What-the-hell if she is putting a lot effort at trying to convince you of her new ideas.

PS: Sorry the question was for the O.P. @MrBonjangles. lol!
