According to you the calling of obvious fouls is to be ignored in a blowout, no matter how obvious those fouls may be.
I agree with you that the ticky-tack stuff and the non egregious/minor fouls will often be ignored, it is never okay for officials to turn a blind eye to an obvious foul no matter how much of a blowout the game may be. The game immediately losses integrity when an official does as you are promoting.
