 ::I did some copyediting to squeeze it in there without adding too much detail, but I would be resistant to doing much more. Currently there is 1 sentence for each side of the argument and if you add too much detail about information that's proving his point, than we have to add more detail from the other perspective. The end result is a big waste of time creating an undue issue and you leaving frustrated that every time you suggest edits to support his POV, we will naturally make edits from the opposite perspective. Of course you are free to do as you will, but my advice would be that it's good enough at this point and a good time to leave it be for the time being.
