LL all I see is them giving opinion. It is basically saying some obscure fact that make a possibility then stating this is what they believe. In my book printing something does not make an arguement. For example I could print seragate invitro fetilization is adultry. Thats not an arguement. If they print "Jesus died on a pole" , that does nothing for their arguement that he did. I mean one citation says basically the equivalent of humans are mammals, dogs are not human, and therefore dogs are not mammals.
Maybe I am reading these quotes wrong, but I think there is a difference in knowing vs believing. The watchtower likes to make them synonyms. Most of their arguements start off there is controversy regarding X, and therefore you should believe Y just because we say so. Evolution, stem cells, IVF, cloning, neo babylonian chronology whatever they are out of there league in. If the watchtower was allowed to tell JWs how to vote (they can't legaly) they would say something like, "there is a controversy about bush vs kerry. bush has ridden in a fighter airplane. Vote bush." I hope i am not sounding hostile.
