It is hard to reason with someone like Fisherman who is bound by his mental model.
Jews would not talk to Samaritans, call it religious discrimination. Samaritans were seen as ritually impure or unclean.
Still, the woman refers to their ancestor Jacob. This shows she did not distance herself from her religion. Her problem: being Samaritan.
Jesus appreciates her honestly regarding her husbands and current partner. John 4:20 shows that she is aware of the differences of where worship should take place ( mountain vs Jerusalem, home/heart vs kingdom hall).
Verse 21 shows reply from Jesus where he shows that both groups are wrong (can you imagine...the gb of the wt to be wrong....). Jesus makes it clear that honesty is key for god (worship in truth = honesty, in spirit= everywhere, not a physical location).
Jesus already mentioned her honesty. Then the woman says she is looking for the messias as he will tell her everything. A very humble expectation. Much different from the attitude the Jews had.
Verse 39 shows that the Samaritans listened to her and went to meet Jesus. Imagine elders in jw land would listen to a woman let alone a woman who lived with a man unmarried.....
Jesus stayed 2 days.
So, no, the woman was not shunned or seen as outcast by the Samaritans. They believed her words. I guess because they knew she was an honest woman. This would never ever happen in jw land.
Jews just avoided Samaritans in all aspects. Pure religious discrimination. WT policy is that woman like the Samaritan woman should be df'ed and as a result shunned. WT will never believe Jesus would talk to such a woman, only to gb members. WT policy is that anyone outside the org is wordly and of less value.
The Jews shunned this woman like WT would.
