Based on this philosophy, should we be surprised that jws feel (wrongly) justified to hate people they have individually (without authority) judged. The WTS teaches that Christendom is full of apostates. I wonder why they even bother to "preach" to non-jws.

Regarding them, the psalmist said: “Do I not hate those who are intensely hating you, O Jehovah, and do I not feel a loathing for those revolting against you? With a complete hatred I do hate them. They have become to me real enemies.” (Psalm 139:21, 22) It was because they intensely hated Jehovah that David looked on them with abhorrence.Apostatesare included among those who show their hatred of Jehovah by revolting against him. Apostasy is, in reality, a rebellion against Jehovah. Some apostates profess to know and serve God, but they reject teachings or requirements set out in his Word. Others claim to believe the Bible, but they reject Jehovah’s organization and actively try to hinder its work. When they deliberately choose such badness after knowing what is right, when the bad becomes so ingrained that it is an inseparable part of their makeup, then a Christian must hate (in the Biblical sense of the word) those who have inseparably attached themselves to the badness. True Christians share Jehovah’s feelings toward such apostates; they are not curious about apostate ideas. On the contrary, they “feel a loathing” toward those who have made themselves God’s enemies, but they leave it to Jehovah to execute vengeance.—Job 13:16; Romans 12:19; 2 John 9, 10.
