First of all, don't become enraged. I don't think it's about giving anyone "power".It's about controlling your emotions. Getting angry gives the negativity of the experience, "power". The angrier you get, the more "power" you give TO THE EXPERIENCE.
Second of all, is this really something that we have to "win"? I think that this is a mistake that many make. This is not "do or die", "win or lose". This is about getting on with OUR lives as best we can. I don't think "the truth" will ever completely leave our minds, so there is no use struggling.
When a situation reminds us of our experience(s) in "the truth", just acknowledge it, don't fight it, and accept that it was once, and may still be, part of your life.
When you deal with relatives or friends in "the truth" how do you expect them to behave towards you? Like a Catholic? If you expect anything other than them behaving like a Jehovah's Witness, then you WILL be VERY frustrated, indeed. Hope this made sense, and I hope it helps.
