My daughter has a "lazy eye" ... sometimes it is straight, other times not ... so we retouch for her sometimes. If her eye was permanently "not straight" then I would be more inclined to NOT straighten it. Same goes for other temporal things like acne or a "slight" weight change, or a bad hair color.
For those things that are more permanent (like scarring), I'm feel that miminizing their distractiveness can be appropriate, but totally removing them then becomes a false rendering.
In reality, we learn to "look past" such "defects" as we learn to focus more on the person than the defect. They are still there, but we just don't focus on them. Likewise, minimizing (but not removing) 'defects' in an image emulates the "they are there, but we have more important things to look at".
That's my basic philosophy on the matter, but there will still be people who want it totally different from reality. It's their pic, they can have it their way, but I'm not a big fan of turning my grandmother into a barbie doll via PS. Whether a person uses makeup (a different daughter with rosacea), or a "push-up", or use of angles & lighting, SF technique, or PS ... it's all fair game as to how to render them ... use it judiciously.
