Point 2 - I'll indulge you here. The Moody / Marx incident looks dodgy to me. Moody does make contact with Marx's head. However, Marx is falling (quickly at that) and that could be seen as mitigation. It is however still worth looking at. But what's lacking in your analysis (and I suggest has annoyed some people) is an attempt to be even handed. If you're going to look at Moody knocking Marx you're going to have to look at pretty much every breakdown involving Savea and for that matter Duane Vermuelen and Francois Louw. Due to Garces being very generous about clean out technique (do whatever you like) those three players got absolutely battered. I'd bet decent money that if you gave me the full match footage I could find evidence of Etzebeth or Mossert (or a.nother) belting Savea in the head / neck at a ruck.
If Garces was biased, why was he? What's the motivation? The only one I can actually think of is that Erasmus would be better off keeping his thoughts on refs to himself. By stating boldly that the All Blacks get better treatment what did he think Garces would do? Red card the whole team to cheer him up?
If Garce's was biased he could have done a hell of a lot better job of it, at a stretch there were a number of incidents where a biased ref could have handed out penalties or yellow cards.
I think people struggle to understand the difference between bias and not being up to standard.
With regards to point two, I think Hansen's comments on Stuff fairly well cover these issues.

"Fiji didn't have to go via social media to go to the judicial committee," he responded. "You get asked after every game, 'have you got anything you want to put up'? If you feel like you've got something to put up, you put it up. South Africa obviously didn't feel like they had anything and we didn't have anything and the citing commissioner didn't see anything."
