obviously this CULT lacks that and teaches how to hate and hold grudges. ALSO how to judge those but wishes not to be judged at the same time. That is CRAP!
To hold 'righteous hatred' is a belief of the JW's. A 'true christian' would hate anything/anyone that God would hate. One who has been expelled from 'God's flock' would be hated by God until they repent and return to 'the fold'. Thus, to uphold their christain standing they will act as though they hate the course of conduct of the expelled person to the extent that they won't be around the person.
Usually they don't actually hate the person (or probably their aleged conduct either), but they act as though they do becuase they're taught that to hate in this way is godly and good.
They align this thinking to lots of bible verses, probably all out of context and misapplied I suppose... but they use the book to preach this sort of godly hatred of people in the way you describe.
And there seems to be a greater tendency for disassociation to be infered from conduct too... don't go to meetings, be seen at a lottery counter and 'BOOM!' you're trated as dissasociated all of a sudden by anyone who's heard the rumour and chooses to draw the inference and then applies their dilligent hatred routine.
Or somthing like that anyhow...
It's a bit borish really. Thuggary. Bullying. Abusive. Rude. Annoying. Petty. Childish. Insulting. Silly. Self righteous. Self indulgent. Wank.
