The Watchtower can be accused of creating many things (e.g., counting time door-knocking! ) But, no way did the Watchtower create a false god at all Perry.
That false god was already "created" and notoriously "present" in the quivering hearts and minds of millions upon millions of believers. Thunderously terrifying sermons down through the centuries and heart-stopping persecution in the name of the Divine monster testify to the "exstence" of the monster who pre-existed by millenia the cranky Watchtower end-time take on Jehovah. So don't tell me the Watchtower invented Jehovah. It simply embraced andf promulgated a literal take that was already in people's nervous consciouness.
At worst, the Watchtower simply updated the Old Testament monster - a monster who thought nothing of genocidal rages (in the most righteous terms of course).
We now realize that those monstrous "takes" on what "god" is like are nothing more than social constructions reflecting the thinking of the time. Some say that simply reflects the Old Covenant and that is not what god is like at all. Oh, well thank you so much for pointing out that this socially constructed "loving god" has allowed himself to be reformed and made a blood sacrifice of his son to which humans had better be thankful - if they know what is good for them.
The only difference between the god of the Old Testament and the god of modernity is the latter's apologists are able to use more convincing sweet reason to give the "current" god far better press coverage.
Angry at god? Nah. That doesn't make sense - although that is a common charge. God is "merely" a powerful social construction. Angry at the men (and few women too I guess) who depicted god as a jealous monster? Nah. That image fitted in with their limited thinking. Angry at current apologists who argue and reason more eloquently about the "reality" of the blood-redeemed love of god? Nah. Not angry - perhaps more astonished that anyone with an active thinking brain puts the time and effort into remediating a socially constructed "god" who conveniently changes with the secular enlightenment of our times.
