Being excluded at times is part of the human experiences and many successful people considered themselves to be social outcasts and not fitting in throughout their lives. Being excluded can actually work for you sometimes if you let it.
The thing that makes it annoying with JWs is they claim to be the truest, the happiest, the Christiest most wonderful loving bosom of a religion in the whole wide wicked world.
So when the "most loving people" on earth reject you what does that do to a person?
I used to be offended by it now I see it as a good thing that I never fitted in with assholes.
