Even if it didn't benefit me personally, I would still be happy including them simply based on the fact that the resident clown car passengers excluded them. Given their history of abuse I would say anyone they are targeting is worth considering for inclusion.
Again, not a great reason to add someone to your trust list.
I think it is a great reason. Why shouldn't I add people who are being targeted by abusive nepotists hellbent on preventing anyone else from having any influence in "their" trust system to counter that abuse? Oh right, because your friends are the abusers. Clearly that is unacceptable then, because you don't approve of the results. Anything else turdburgler, or are you all tuckered out and ready for a shower?
