The link up there contains a document file worth a look as well. The guy who wrote it (a good friend of mine) struggled with the issue for a good while whilst studying with the witnesses.
He did not receive a satisfactory answer to his questions, so he gave this document to the society for consideration.
Basically, they never even took the time to address the document and his genuine concerns.
This was the turning point for him and he did not proceed towards baptism because of the arrogance and ignorance displayed by the local witnesses.
