ie, the direction from which the force is generated and how it acts, hence what makes push and pull opposites.
The fact that you are avoiding the example with the pencil shows that you understand
The example with the pencil is a different scenario with different forces applied in different directions.
So if you cut your finger off, would it suddenly NOT be the handle that the pencil is in the example you're avoiding?
I'm not understanding your question. In the pencil example, the pencil is gripped with the full hand (pinky closest, thumb further). Why would cutting a finger off affect anything?
The pencil is the handle of the cup either way.
n my view, and that of classical/deterministic physics - there is no pulling
Every information on classical/traditional physics I'm finding describes distinct, different forces. Where/who is discussing push as the only force in the universe?
ie, the direction from which the force is generated and how it acts
Not in the example, no. Just the direction from your relative perspective.
The direction of the force, from the perspective of the water bottle, is identical.

Nope! Same forces, same direction.
The only thing different when the bottle is facing away from you and when it is facing you is just that. Everything else is the same.
Why would cutting a finger off affect anything?
Because then the finger would be (effectively) the handle that the pencil is. When the finger is attached to your hand (and the fingertip superglued to the bottle, remember), it is functionally equivalent (physically/mechanically) to you gripping the end stub of that severed finger (or end of the pencil) and applying force as we've already described. This conceptualization was to disabuse you of the notion that there is some fundamental difference between the pencil and the finger superglued examples. There isn't, and severing the finger (hopefully ONLY in imagination!) makes that clear.
Where/who is discussing push as the only force in the universe?
You are likely not going back far enough. It is the view of most all classical/deterministic physicists. Most particle physicists into the 50's-60's (and likely some beyond that) shared/inherited that view as well. You may want to do some research on things like magnetic monopoles, and other force carrying particles believed to exist. None of them can pull either! Because billiard balls can't pull! I do hope you are at least beginning to understand me ;(
