Personally, I'm with you. I get tired of seeing the griping about officiating. I call it the "walrus" excuse - WLRS, we lost refs sucked. The walrus is a big, clumsy animal that doesn't really look like it's enjoying things. The same seems to happen with people who constantly complain about the officiating.
Yes, officials miss calls. Yes, some officials are a lot better than others. Just like players. Just like coaches. Until a player shoots 95% from the field, never commits a turnover, and never loses a rebound, they shouldn't be complaining to officials. Same thing with coaches - until they are 95% accurate with their gameplanning and in-game adjustments, just stay quiet unless player safety is an issue. If fans complain, there is a national shortage of officials in every single sport. If they think it's so easy, they can start working games.
It's actually one of the things I appreciate about Underwood over the years. When he came to Illinois, he was ALWAYS griping to the officials. Even as an Illinois fan, I was kind of embarrassed that he was representing the university like that. He still expresses his opinion and gets T'd up every so often, but over the years he's become much more reserved and selective in his interaction with officials.
