As far as I'm concerned, the JW's have become ever more cultier than ever before just in the last 6 months to year-and-half now. The JW who wants to marry a Catholic will face the henchmen in that of their local elders. They have changed a lot of their ''disciplinary'' words to ''brazen conduct'' broadening the scope of offenses, they are a lot quicker now to disfellowship(excommunication). It's up to the local JW gestapo what punishment they will administer though.
Shunning is now enforced to a stronghold, so any relatives including your immediate family not living under your roof will ostracize you at will. Remember, once you sign your life away by baptism, it's a life long contract. Shunning a JW family member takes precedence in practising loyalty to the cult.
