I'm glad you find it all "very interesting."
Officials, by and large, are jacka****. And I wouldn't compare to the rest of the population. Certain folks gravitate to positions where they can exert authority. Some officials are just jaded by doing it for too long. Many just don't have the temperament. Some are just doing it to make extra money, and not because they love sports or even care about the kids.
Many forget that in the youth context, they're the only ones getting paid. By and large, jack***s.
And as far as the fat reference, which I guess you're offended by (whatever ... someone's always offended), that's to highlight that he shouldn't even be on the floor. He was way overweight, out of shape, and can't even get up and down the floor to do his job the right way. You actually see a lot of fat refs that kind of waddle around. It's a disservice to all involved .. except of course the ref, who gets paid regardless of his performance. Not so sure what you found interesting about it. Fat people are limited in what they can do. Harsh reality of fatness.
We had one fat umpire we called Jaba the Umpire -- worked all the time, never once ran anywhere. He couldn't. Just an absolute affront to the game. And he was one of those "my field" and "I'm the boss" kind of guys. Not a bad ump if you planted him right behind the plate (other than attitude), but he couldn't do his job in the field. He apparently shined shoes or was a barber or something like that during the day -- umpiring was his opportunity to be the boss.
It's also comical when you talk about a referee's view of things. Multiple times over the years I've had circumstances where I've seen, heard of, or been a part of officials (baseball, basketball, football) being confronted with video --- they don't want to see it. It's a joke. Not once have I ever seen, heard of, or been a part of an official in any sport saying sure, let me look, and then saying, wow, I had a different view, sorry I missed that.
I have had officials, mainly baseball, concede later in a game that maybe they missed something. Those are very few, very far between. Why? Because the instruction they receive is to NEVER concede. I've been to the clinics. I've seen it first hand. To suggest you might be wrong, or might have had an obscured view, or are anything less than 100% correct is a sign of weakness and compromises their authority over the game -- that's close to a quote.
And remember, when you're dealing with a drunk fan, YOU are getting paid. And yes, you do have to deal with fan issues if you sign up for the job. Players, coaches, fans have passion. And for each of those three groups, they have invested a lot of time and energy in their endeavor -- and they generally pay to play.
