Why is being called weird the thing that pisses them off? Some thoughts...
I mean, it honestly makes sense. Why do people join a cult? Mostly, for a sense of belonging. At least in my history of dealing with these people (and cults have always been a bit intriguing to me for several decades now), a lot of them were having trouble with their own lives and felt a bit marginalized to begin with. That's the more vulnerable time when it comes to being indoctrinated by a cult. So they find people they fit in with, people that understand what it's like to be marginalized because no one's life was going well, and they ban together and suddenly they are part of the in crowd (in their eyes), they have this new cult family, all these new cult friends, they finally fit in, they have all this secret knowledge that only they are privy to, they have finally made it from zero to hero in no time flat just like Hercules-- then you have someone who finally says 'no, you're not part of the in crowd, you guys are out there in left field, being weird, you just found a bunch of other weirdoes like you'. Suddenly, their sense of belonging, which is what they were looking for, is called into question. They are faced with the possibility that their newfound family and in-crowd status might be just an illusion, which can be very destabilizing. Keep calling them weird, it might shake some of them out of their delusion. Maybe...
