"We don’t use the word, shunning"
How about the following four Watchtower instances?

SHUN BACKSLIDERS AND LIVE!
24 "Do not be misled. Bad associations spoil useful habits." (1 Cor. 15:33, NW) Ancient Israel was warned not to companion with the demonistic nations round about them. But Israel did, and Israel was contaminated. Israel fed on false doctrines and slid into a morass of sin. Only a faithful remnant resisted and stood fast. It is the same today, for what happened then is prophetic of today. The majority are feeding on spiritual food that failed to nourish in Bible times and is failing to nourish now. So there is a spiritual weakening and backsliding afflicting the majority. But there is a small minority holding fast. Those wishing to avoid backsliding must shun the backsliders, for such bad associations would spoil useful habits of true worship. Do not be misled.

Furthermore, some of the religious literature that people may urge Jehovah’s Witnesses to read is written by, or contains the thoughts of, individuals who have apostatized. True Christians are commanded to shun such apostates. (2 John 9-11; Titus 3:10, 11)

The same was to occur with apostates, such as Hymenaeus: "As for a man that promotes a sect, reject him after a first and a second admonition; knowing that such a man has been turned out of the way and is sinning." (Titus 3:10, 11; 1 Timothy 1:19, 20) Such shunning would be appropriate, too, for anyone who rejects the congregation: "They went out from us, but they were not of our sort; for if they had been of our sort, they would have remained with us. But they went out that it might be shown up that not all are of our sort."—1 John 2:18, 19.

Loyal Christians have Biblical reasons for shunning apostates and their views.
