Not quite convinced, but I need to spend time looking further into this and respond later.

Here is another logical fallacy:
First you say that you can not shield gravity forces, but at the same time you claim that the negative charges inside the sphere are shielded somehow. In common electromagnetism, the negative charges inside the sphere are not shielded by positive charges around the sphere.
Not my point, really. Outside the charged sphere there is a surplus of one
charge, as the previous illustration shows. The internal charges reduces (but doesn't cancel) the absolute value of the surface charge, compared to if the sphere theoretically consisted of only
one charge. Inside it, an internal shell of negative charges would assert no net force on a charged particle located within, so the E-field inside it is described as being zero. As a side note, one could argue that the shell has a repelling/expanding effect on itself though, which makes an interesting case for the central interior of a planet.

The electrical field of the inside negates the electrical field of the outside. This works even at close distances, because the 1/R^2 field is exactly the opposite of the area that the charge is distributed over. As long the charges are evenly distributed.
You now seem to claim what you just opposed, by saying that the inside zeros out the field of the outside (although that wasn't my point). The important part is that there is a difference in distance
. The more distant opposite charges (of equal amount) of the inside won't subtract the closer charges at the surface down to zero or below. The absolute E-field value will always be above
zero. This is why it is called a charged sphere
, because the exterior has a measured E-field.
