That’s the point though. The system has features that can correct things. Like appeals."It should also not be denigrated or called into question if a decision doesn’t go the way one wants it to"
While I understand the nuance of what you mean by this (and I agree with you) this is of course the basis of the entire concept of an appeals system.
If the system is rigged in the minds of some then logically in their minds so would be the appeal process.
The problem is people pick and choose and what they think is rigged.
