You think you can improve others? How's that working for you?
And going round and round bothers you? Then get off the merry-go-round. Nothing says you have to stick around. And you're goal is to learn? Since when? Not many threads on this site that give the possibility to learn, but I don't see you there. (Nothing wrong with that. Like I said, not may around, so there starts to be expectation of nothing to learn. That means most of us are here to do something else other than learn!)
The best I can do with true trolls is to cut down on their excuse list. That's my thing. Willie has a cool idea -- friend them. It doesn't have to be the goal of learning.
But anyone who spends their time in that much rage is hurting. Why flame the pain? And if you do flame, doesn't that make you a troll at that moment?
And again, no one is open to hear God. That's a given explained in John 3:16-21. We don't want anything to do with God but he lights us up anyway.
Of all the come-to-faith stories I've ever heard, the commonality was, "I was angry, left, and somehow God got me when I least expected it." What makes them (us) angry? Some fool thinks God is real. What are you expecting coffee and cookies from someone who thinks you're an idiot? That might happen if you meet them again after God's light comes on them, but not going to happen when they're angry. lol
