I have loads of time for JW, mormons, etc. If they knock on my door I welcome them in and chat for hours (at least partly because one of them was very very tasty). I like to think that I have a better knowledge of biblical matters than most of them, and we debated for hours at a time. It is only when we reach the point that I compel them to condemn a translation such as J.B. Phillips as apostate that we have to part company. And all that fuss over John 1:1 - I really can't see the problem with it either their way or the traditional - how on Earth can a father and son be in existence together from eternity - where is the begetting process in all this ? Either way it is rather tedious doctrine and detracts from more crucial issues.
JW and mormons are very nice people, I'd rather meet a group of them in a dark alley at night than most other people.
