This comment doesn't track the argument in the comment it's responding to. It happens by using a different reading of "proportional" than the one that was intended.

The results and outcomes alluded to in each comment, mine and the one you're responding to, are consequences of essentially begging the question. It's that part where the flaw lies—because it leads, as in your comment, to justifying things as rational and fit even when they are not equitable.
