I'm not sure why roundabouts are so uncommon in North America.

Where I live, at a 4 way small street intersection, two of the entrances have stop signs with a roundabout in the middle. At that point, you might as well get rid of the roundabout.

I think I live in a typical US CA city and there are dozens if not hundreds of roundabouts in this suburb. And I don't understand why you would have stop signs AND a roundabout. I am hoping someone can explain this feature to me. It just seems like extra chance for confusion and extra source of danger because of that.

You shouldn't. It's a poor design choice to cater to Americans who aren't used to roundabouts and yield signs. It makes things less safe.

The only situation where I could see stop signs making sense is an unbalanced roundabout. It can be hard to get an opening to enter a busy roundabout that is dominated by cross traffic flow.

I have it even worse near my house. A roundabout with a stop sign at every entrance. It actually causes more problems than a four way stop sign, because people enter without signaling and then get mad when you assume they're going straight.

There is literally no difference between someone going straight and someone turning until they are right in front of you (unlike with a regular intersection where they would at least angle the front of their car to indicate turning).
