Hi Esmeralda,
Wow, keep these very entertaining stories coming!
These women in the religion are angry because you are not allowing them to get to you. You are refusing to be victimized and this is frustrating them to no end.
The game they are playing requires two parties: the person playing the role of haughty persecutor/punisher AND a masochistic victim who accepts their role.
They are annoyed for another reason (that they would never verbalize): they think they are better than you. By you adopting a dignified stance and ignoring them, this makes them furious. The fact that you are young and doing this angers them more. They imagine you should just sit back and take their disrespect. You have "stepped out of line" in their eyes because you aren't. They may hate you forever.
As somebody who came from a somewhat dysfunctional home, plus spending decades in the workforce around countless catty, backstabbing women and also in the JW religion with the same ruthless games, I am expert in this area, sorry to say.
You are going to have to develop a very thick hide to be in this religion! I got weary of it.
