Dear Getting,
Many of the JWs doctrins are based on typical fundamentalist literalism, hence, taking the OT literally regarding a racest, nationalistic diety is not too hard to understand. Once one rejects the Dubs and their peculiar blend of OT/NT rule making and control, it's not too suprising that one might call into question the whole bathtub of dirty water as being hogwash. I know I did and quickly became agnostic after leaving. If one can step back and look a the progression of expression in the OT the NT and the Koran, you will begin to see a developing understanding of the relationship between the godhead and humanity as well as the reality of the "mediator".
Since the Koran even more challanging metaphisics have emerged. I find them able to reconcile the apparent antimonies mentioned above in other posts.
Hope you can overlook the slights to Jah, and tolerate those who have been battered and bruised by those who carry His name.
cheers,
carmel
