Oh alright, I'll say something.
Point 1. His claim of running the gain up until the channel flashes red and then backing off a touch is assinine and in no way is an appropriate description of proper gain adjustment. On a decent analog mixer, proper gain adjustment leaves 20 to 24 db of available headroom when the gain is set to meter the channel at 0.
Point 2. The "author's" comment about the studio and running all faders at unity. Duh - If the tracks have been properly recorded, they should all display very nearly equal signal level at their peaks. Setting all faders at unity should present a "pre - mix" of approximately equal levels on all tracks - a pretty decent starting point which has damn little relation to live mixing, unless of course your recording engineer likes to record his tracks to emulate all the problems presented by variances in stage volumes between various instruments.
