I can put up with shunning from pretty much everyone but it cuts like a hot knife when it's a parent or for kids - a grandparents. How do you explain to children why Grandma hates us?
The psycho-religio mind virus WT installs in people's brains is pretty damn good to be able to bypass the natural maternal instinct to love and protect so effectively in otherwise "normal" people.
Truly evil what WT and cults like it do to family.
