As an outsider to this whole situation (having never been involved at all with Boston Kentucky or any of its chapels), I don't know the history very well. And I am not really entitled to an opinion, but I'll give it anyway.
It would seem, from this thread, that Mr. Chavez has seen what Boston, Kentucky is really all about, and has distanced himself from it, thankfully.
Can't he be forgiven for his mistakes? He probably needs to ask for that forgiveness, but still. Aren't we supposed to forgive our brother 70 X 7? That sounds too simplistic, I know. It appears that he stayed involved for too long due to familial concerns (and other reasons, too), which he has explained. That seems reasonable to me. Family ties can be a powerful motivator, and not always to the good.
