Yes, this situation and religion is crazy - NOT YOU!
Although everything you said to the Elders and others at the hall is all true, they don't want to hear it and will NEVER want to hear it as it is upsetting to their concept of their True paradise religion.
They will never give you praise for pointing out their shortcomings or errors, so stop expecting a positive reaction. You will never receive it from them.
You can't control or change how others will react to a matter. The only change you can effect is your own.
You appear to feel guilty and responsible for your husband's deletion as an Elder which is likely affecting your ability to speak frankly with him. You also appear to be looking for others, anyone, to validate your ideas, actions and value as a person. These are self worth issues which are understandable given your background but these and trust issues need to be addressed by your therapist.
Regardless of how others react, your thoughts and ideas are equally as valid as anyone's.
You are a valued member of society and a good person! Stop thinking of yourself as less.
If your current therapist is not helping YOU, then find an alternate therapist who you feel comfortable with and can trust, that you evaluate is helping you and effecting positive change.
You mention looking at the dictionary for the definition of harassment. Since the elder's actions are affecting you, regardless of the dictionary definition, do YOU consider his actions to be harassment? How you feel is most relevant.
If his actions persist, you may wish to pursue pressing harassment charges or obtaining a Restraining Order against him. He is not your friend as a true friend would not treat you in the manner he has.
While you refer to being trapped in a prison, the door has been unlocked for some time. It's time to leave, both mentally and physically.
