I guess what I don't get is why the WT defined neighbor at all? Why just say our neighbor is everyone and here are some examples of how we can help. Seems like it would have been simpler and easier to understand.
By defining the word neighbor and giving three categories they did in fact exclude those not in one of those groups. I guess when a witness is out of their KHs territory they don't have to treat everyone like a neighbor because they wouldn't be preaching to them.
IMHO almost every witness at the meetings understood what was really being said - we treat our families, fellow believers and those we may convert as neighbors - to hell with the rest of them.
