You're confused, not 'confuced' (sic)

You've obviously confused them here, but there's no reason for me to believe that Truthiness has made the same elementary mistake in reasoning of which you're guilty.

Which reasoning was that?

The reasoning that led you to equate sensor size to pixel size and pixel count. I think it's obvious for all to see, and, as Truthiness has confirmed, your interpretation of his remarks was wrong.

That is the smaller pixels on a smaller area with "stress" the lens more, than the larger pixels on the larger area.

Do you think that the sizes of the image circles that the respective lenses and sensors are designed for play any role in this "stress" equation? If so, how would you describe the role they play?

The size of the pixels (not the image circle).

Let me get this right - you're saying the size of the image circle plays no role in this equation?

Smaller the pixels the better the lens must be. I can see it on D800, some lenses are considerably better on it (when compared against 12MP cameras), whereas others are only marginally better (as few old wide open fast primes for example). That's what I thought he meant in his post.

He's confirmed what he meant now, and it's not what you thought.

thus the lens can be of lesser quality to achieve the same image quality.

Lesser quality in what respect?

As stated above.

Nope.

Generally yes.

"Nope" refers to your misinterpretation of Thruthiness' words.
