I concur with Gary - JDubs split up families.
If you are filled with pride and dignity, I think reverse shunning is the answer. If you are sheepish then reverse shunning isn't for you.
Regarding the children - If the children WANTS to see the Jdub family it's their choice. But children aren't blind to reality, they can see how the Jdubs treat their parents or love ones and the effects it cause, why would the children want anything to do with Jdub shunners?
I look at it this way - Jdub shunning reminds me of racist groups. Racist groups want nothing to do with you (folks outside their group), view you with contempt, pity you (maybe), feel they are justified in their negative actions, twist scripture around to suit their agenda, wish or can't wait when you are disposed of, would always caution their children about you, would ignore you in the street like you were invisible, will never give you the benefit of the doubt, assassinate your character, deal with you strictly on a limited basis, etc.
The same way I wouldn't try to gain the approval of a racist, I wouldn't try to gain the approval of a Jdub - Just not worth it.
