Image resolution is the detail an image holds. Higher resolution means more image detail.

You have to explain now what "detail" is, and what it means for an image to "hold it".

As I pointed out in this example... Number of lines. Simple stuff. You get the same count either picture.

At what angle? What contrast? Which color channel? Even if you answer all that - why would that be a measure of resolution, and not of aliasing? Why not circles instead of lines? Or points?

In scenario B, as presented here, only the line count mattered as that was the only detail present. A and B were in fact the same regards resolution. Pretty obvious that angle, contrast, and color channel had no bearing on resolution in that example.

Then you have a definition of resolution which applies to one example only?

Yes, I have only been discussing the specific scenario b in this line, as it was presented. I found it a good simple example well made for diffusion. Makes it easy to see the difference between sharpness and resolution from a common perspective
