I don't recall you ever saying anything about this to me - I've always had and said the same thought.
I've always agreed with this too.
Who has claimed that? Not me. What I have said is this: no matter how you get the tip there, it has to hit the same spot on the CB from the same direction to get the same results.
Yes, if measured from the same viewpoint - the direction of tip travel at contact.
Not when measured from the same viewpoint.
And what's "parallel" english? What's parallel to what?

We are never measuring from the same viewpoint using different forms of applying spin as each one results in a slightly different head position. For purposes of this discussion which is already trending south with your denial of understanding exactly what parallel english is, I'll point out four viewpoints if your line of sight is directly above the line of the shot.
Looking down the shot line with no english applied, we will call this viewpoint A, Tada!! This is also the baseline, perfect viewpoint to make the shot with no spin applied.
We will call the viewpoint using FHE viewpoint B since it is closest to viewpoint A.
We will call the viewpoint using BHE viewpoint C since it is second closest to viewpoint A.
When using a parallel shift with no pivot point to move the cue stick we will call this viewpoint D since it is furthest from viewpoint A.
I am only talking about our head position when saying different viewpoints are different distances from viewpoint A.
OK, now we will see why I established these baseline definitions. If we maintain our head at viewpoint A or return it to A after aligning the shot, it becomes possible to see that from this original viewpoint to hit the cueball with no spin, it is possible to hit the cue ball further out with no miscue when the cuestick is moved parallel to it's original position than it can be with any point of the cue shared with the original cue position.
A parallel shift has resulted in zero angle change so we can hit furthest out on the surface of the cue ball using this form of side. FHE creates less angle than BHE so the surface of the cue ball can be hit further out with FHE than with back hand english. BHE creates the greatest angle of the three methods so the surface of the cue ball can be hit the least far out of the three methods discussed.
Any or all of these methods can be combined. When I use front hand english or parallel shift english I sometimes make tiny adjustments with back hand english. Just for grins I have also applied all three forms of side for awhile practicing. It works but is needlessly complex both mentally and physically as expected.
Review for PJ:
BHE: Side is the result of moving the grip hand side to side with the physical pivot being at the bridge hand to establish the new contact point.
FHE: The bridge hand is relocated to the side with the grip hand in the approximate position it would be shooting without spin to establish the new contact point.
Parallel English, AKA Parallel Shift English: The entire cue stick is moved to the side with the angle of the cue stick remaining the same as it was before applying english to establish the new contact point. The cue stick is parallel to it's original position.
If the exact same point on the cue ball is hit using the three different methods of establishing the contact point, it will give three different results due to three different cue stick angles and three different directions of force.
