To be honest, I do feel an intense dislike for certain ones at times. If I remember certain instances then I can become very angry and hateful but that's my problem that I'm trying to work on.
I only hurt myself by being like that after all and no I haven't worked out my ill will torward them. If I did then it would only feed my anger and cause myself more harm as you are so right about it being bad for your health.
There are some witnesses I knew that I liked so much and am so upset I will never see them again. I didn't know them very well but saw their behaviour and overheard a few comments. They really stood out as being non-judgemental and nowhere near self-righteous.
I guess the fact that this made them stand out meant that on the whole the witnesses don't usually own either of those qualities. I wish I told them how much I liked them and wanted to be like them as they weren't very popular and usually had an air of sadness.
I think my view of Jehovah's Witnesses in general is that I'm not really that keen on them.
