Hey bluebeads,
In the "Organized To Do Jehovah's Will" book on pages 157-158, it talks about unbaptized publisher's and wrongdoing. If the UB is unrepentant, an announcement is made that they are no longer recognized as a UB and cannot turn in field service time. They are viewed as a person of the world and its up to the individual JW to associate with them or not based on 1 Co 15:33.
However as stilla said, they can't shun you because you are not baptized, but most JWs I know, they will take a hardline stance and probably shun since they think they are following 1 co 15:33. Depends on what kind of pressure the elders will put on your family if they continue to associate with you.
Good luck,
FA
