It is wonderful that you are truly seeking viewpoints and rationales so as to be well-informed.
Most often those who criticize this particular doctrine are totally closed-minded and I regret that I place you in that category.
I hope my words gave some insight into the doctrine and how one can think about it - and that you can see past any words that may seem harsh or impatient.
I yearn to understand, and I appreciate your help.
