Give it back to these bullying elders in spades. Caleb's mother provided us with the best righteous 'beat down' of all.
Mom: '.. you don't want to make Jehovah sad, do you?'
Caleb: '.. No.'
Mom: ' ..I don't want you to make Jehovah sad either...'
Now back to your 'bully elder'.
scene #1
You: Brother Bully, I noticed you parked too close to the lines in the parking lot. Now someone will have to fight to get their car door open. That will make Jehovah sad. You don't want to make Jehovah sad, do you?
Br. Bully: Hunh? No.
You: I don't want you to make Jehovah sad either.
scene #2
You; Br. Bully, I noticed you didn't properly wipe you feet when you walked into the Kingdom Hall. Now someone will have to clean up after you and that will make Jehovah sad. You don't want to make Jehovah sad do you?
Br. Bully: Hunh? No.
You: I don't want you to make Jehovah sad either.
scene #3
You: Br. Bully, I noticed you didn't look up all the scriptures with the speaker during the public talk. You looked up 6 but missed 4 others. If you set a bad example to the congregation it will make Jehovah sad. You don't want to make Jehovah sad do you?
Br. Bully: NO !!!!!!!
You: I don't want you to make Jehovah sad either.
You get the idea. Be creative, use your imagination, always looking for a lesson to teach Br. Bully.
How can anyone argue with your logic? It wins every time. It's perfect WT speak. You are always the righteous one, always on Jehovah's side. Pick a bully and ride him. Drive him into the ground. Give him a good taste of his own medicine, but in a nice, theocratic way.
