i would have to say that, just like every other religion, you gonna get those a-holes who are so fanatical about EVERYTHING that they can be persuaded to have "no natural affection" just like the people their so against. you know the saying, "if you don't stand for something, you'll fall for anything"?
some people are just like that...they take everything to extremes, they don't think for themselves, they can be persuaded to do almost anything...i think a lot of the people you're talking about is like that...
in my family, my sis was dis'ed by the congregation for rediculous behavior, but my mother didn't disown her. neither did i. we're still as close as we were before...we just don't agree with what she does in her personal life...we still hang tight, though.
so your statement doesn't hold true for all JW's...just the weak ones.
