Totally agree with Onager on this. It depends on the family members and friends of this young person. Take for example my husband's cousins, they were all raised as JWs. Two got baptized, while the other three did not (all siblings). One is still going strong as a JW and has a very typical JW mental attitude about the rules do and don'ts. The eldest never got baptized, she would have been disfellowshipped for fornication if she was. She had a good relationship with all her JW family until her death due to cancer. The second did get baptized, but she did a successful fade, she too has a good relationship with all her family, including the JWs. The third girl also was baptized, and she is the die-hard JW, who doesn't have an issue shunning those who leave or are kicked out. The last two never got baptized, and don't even attend meetings, both of them lived with their partners for many years not married, and one even served in the military in Desert Storm. The active JW still has a very good relationship with all her siblings because they either never got baptized or managed to find a successful way in fading. Yet on the other hand, if my husband, who did make the mistake of getting baptized, even though he did not want to, but because of peer pressure, later dissociated himself. This same JW I am talking about grew up with him and spent quite a bit of time with each other as kids, does the typical JW shunning with him. He never did anything that would cause him to be disfellowshipped, he just disagreed with their teachings, and always has. The biggest mistake he has ever done was getting baptized, he said.
Me on the other hand - My mother told me that she would still shun me even if I never did get baptized. The witch would love to stone me to death if the law of the land would allow of it, and yes she told me that a few times and that was even before I left that cult.
