This research has confirmed for me that religion is supernatural superstition exploited by a few in order to manipulate and manage the masses.
When said like this, it does sound harsh. I agree, and I also agree that some people do need hope, and explanation for what they fear, comfort, structure, a place to belong and a sense of community. Personally I always make a distinction between what a given religion teaches and what it does for their people. They can worship Mr. Potato Head for what I care, for as long as they bring some goodness to their people.
The control of the masses is a separate effect. There are well intended, welcoming religious groups that look to serve their people, not exploit it. They may not be as visible, but they are. I've myself have come to learn that.
Question: is there any reason why you seem to be studying mostly Judeo-Christian religions? I think that you may get a better sense of what religion in general serves to people if you expand the denominations (just curious, not criticizing).
