Ritualistic shunning by Jehovah's Witnesses and other extreme religions is not really any different than its blood doctrine or the primitive religions that practice handling rattlesnakes, engaging in honor killing and requiring women to be covered. In each case, power and narrow exegesis rather than love and compassion, are the motivations. Christianity is not about shunning and making people miserable, but relieving their burdens and to commiserate with those whose only infraction might be disagreeing on a point of doctrine! If someone is angry and constantly trying to destroy other peoples' faith in the church, I can understand why members might want to avoid them. But families and friends who ritualistically turn their backs on people because they've been ordered to by petty local officials don't know Christian doctrine or teachings.
Whether someone associates with such is up to the person doing the shunning, not the church elders. Nowhere in scripture are elders or other overseers authorized to create enemies lists and dictate this kind of behavior. It's nothing but mind control coupled with unrighteous dominion. It not only passes dictatorial authority on to elders that they don't have in the scriptures, the verses used by the Jehovah's Witinesses to justify shunning is counsel given to individual members, not direction to local church leaders to make that sort of determination. There's also the element of free agency, because if everything is dictated and micromanaged by elders, there is no free agency. No room to show individual compassion and love.
Jehovah's Witnesses need to reexamine this entire control issue and take back the ability to be free agents unto themselves, because this is what God is all about. It's why God doesn't stop all evil, put an end to poverty, disease and keep wicked men from exploiting those they control. Just the thought of someone dictating to me whether I can associate with a good friend or my family makes my blood boil.
