Ah, the Kingdom Hall of Atheism. That's where I feel like I am as well sometimes.
I'm with crossquestions6995 on this. I've noticed the same. Perhaps I'm contributing to the perception in not entertaining the arguments. I probably have a perception that could be of interest and can't count the number of times I've thought about throwing the metaphorical curve in with an explanation based on other scriptures. The problem is, participating is like going to the KH for a service. I'm okay with a person having a belief (or non-belief) that I don't share. I just can't stand the venom.
It seems that those who bash may once have bought into the notion of the scriptures being entirely literal. That's the WTS's fault given their use of the Bible as the strong arm of laws they're trying to bind on the conscience of the adherents. It seems that once the holes of the literal interpretation of passages such as Noah's Ark and the book of Genesis are realized, there's an entire collapse in a belief in a higher power.
In other denoninations, the literalism of the Scriptures isn't stressed like it seems to be in JWism, so I've figured that's the angst.
Oh, and no, I'm not participating in a "well WHICH parts are metaphorical" discussion. While invited repeatedly, I rarely stay long in the Kingdom Hall of Atheism.
Still love you guys... but you can enjoy your own service. LOL
