Been there and had a whole attic full of trophies. I showed my Fox Mustang everywhere from MCA Grand Nationals to local "charity" type shows and also judged quite a few shows. That said, I'll say I have indeed seen the behavior described in the op's posted link as well as a lot more not covered here. Some people take this stuff very seriously, just human nature and comes with the territory. Most shows offer a copy of a participants judging sheet so they can see where their vehicle fell short. Some take it as constructive criticism, dig deeper to present a better prepared vehicle the next time, them some just prefer to take the other route and blame anyone they can for their failures. Just the way of the world.
