Has anyone else experienced the wrath of Elders and ex-Elders on innocent rank-and-file dubs?
Yes.
What are these power hungry men and their wives so mad about?
Many are tired from working low-paying jobs, disappointed that they are growing older and poorer while the paradise isn't really any closer than it was 40 years ago. When they go to the meetings they're tired of giving so many talks and trying to get others to show up for FS. They tire of befriending and love-bombing other people that they really don't have much in common with or even like sometimes. And they're tired of kissing the CO's and COW's asses every few months. They can't take this disappointment and frustration out of jehovah, the GB, or the bOrg. That just leaves everything and everyone else as targets.
Where is the love we were promised when those witnesses spent hours indoctrinating us about the Spiritual Paradise of Witnesses we would be joining?
The "love" was just love-bombing to get people to join. Then "love" is just a propaganda tool like "joy". They're depressed and emotionally distant, but call them "joy" and "love".
Where are these or "them" who love each other?
There's plenty of love to be found outside the KH.
All I experienced is their hatred and wrath, what should I do, roll away?
You're still a young cart, there can be much more to life than displaying WT litteratrash and advertising their Interwebsite. Perhaps you could replace all that stuff with some nice brochures and posters for vacations or cars! Or, maybe you could go to university and handle brochures for educational programs and financial aid. Whatever you choose, it's likely that you will get much more love and attention than what you've been getting as a JWcart. Also, I hope you're comfortable with people getting all touchy-feely if you become a "worldly" display.
