However I disagree in the so-called strange EM repulsion discussed here but not clearly anywhere else.
How much clearer can you get than this?
wikipedia said:
The consequence of the Pauli principle here is that electrons of the same spin are kept apart by a repulsive exchange interaction, which is a short-range effect complemented by the long-range electrostatic or coulombic force. This effect is therefore partly responsible for the everyday observation in the macroscopic world that two solid objects cannot be in the same place in the same time.

Again, it's not part of QED.
Richard Feynman, wikipedia, and sci.physics disagree. I've given you at least three sources that should be perfectly sufficient to establish what mainstream physics says at this point--one of which is a video of one of the founding fathers of quantum electrodynamics himself.
That EM action can resist gravity action on particles/objects isn't the issue.
This is a direct contradiction to:
However I disagree in the so-called strange EM repulsion discussed here but not clearly anywhere else.
Early in the argument I objected to statements that EM cancels, counterbalances gravity. I did so because it is known that only gravity acts directly on the other forces.
This is a red herring though. I stand on a scale, the springs on the scale depress; the more they depress, the more they push back. Naturally they continue to depress until they are pushing up at about 148 force pounds of pressure. The very principle behind the scale--the way that it works--is to measure the amount of deformation required by Hooke's law
WP for the scale to push me back up--a repulsion by definition--at exactly the force that gravity pulls me down.
Now, the force by which those springs push me up when the springs are at this deformation is electromagnetic in nature. But you're saying that you have a point that gravity acts on the force carriers here. Well, yeah, it probably does, but it's almost entirely irrelevant. The springs themselves have weight, for example. And when they are depressed, they probably do weigh a tiny bit more. But if you take the scale and put its plate against a vertical wall, and you depress it enough to read 148 force-pounds, you're going to have to apply 148 force-pounds to do it. This is a demonstration that the fact that gravity acts on the energy of the virtual photons on the scale is hardly significant.
Now, the scale only depresses this particular amount, because that's all the mass I have. And you can say that the reason the scale doesn't go down further is because there's not enough mass for it to, but you cannot use the fact that there's not enough mass for the scale to go down further to conclude that the springs do not, in fact, push me up. Yet this is exactly your line of argument with PixyMisa.
To put it another way: There are two classes of actions. One is gravity alone acts on the other forces. The other is all forces & some quantum principles act on particles/objects. Some of these activities resist the action of gravity on particles/objects.
Exactly. The electromagnetic force responsible for the repulsion of my weight in the scale, for example, resists the action of gravity to prevent the springs from bending any more than that required to read 148. Likewise, the electromagnetic force in the floor pushes on the scale and I preventing both of us from sinking through to the first floor; and so on.
Or at least, this is the story as told to me by mainstream physicists, of which--do not take this the wrong way--you are not one.
