That's all very well, but as we all know, this forum is monitored by the media, and a frenzy can be triggered by the asking of questions in a pejorative manner such as your :
"why start low with full tanks, on a hot day?"
This might seem, to the non aviator, to be an important question.
It suggests some kind of rashness on the part of the pilot just by the fact that the question is asked.
I can do it too.
"Why start with a vertical roll to the left on an east / west runway!?"
"Why was he wearing green rather than white gloves!?"
It could sound to the uninitiated to be relevant, but patently isn't.
Not all questions are equally valid, and the discussion is not helped by irrelevancies.
It isn't "closing ranks".
It is an effort to maintain clarity.
