I don't think he wants everyone who's not a pro to GTFO, he just wanted to share a dangerous expericen that happened to him. Etiquette and safety are important in the park and outside. Even a pro can act like a gaper in the wrong situation:
A friend of mine was boarding in the park, some hot shot old guy skier comes blasting through the park at really high speed. She falls with one arm out in front of her, he carves over her hand and cuts her index finger off. He never even stopped or knew he did it. She got it reattached thank goodness.
I understand OP's point of view, he's obviously frustrated and just venting here. These stories in this thread remind me of the opening day last year at my mountain where this father took his two young girls (No older than 4 or 5 years old) into the park and let them ride up every feature where they then stopped at the lip, and skied back down. Not only was this dangerous but completely and utterly frustrating as I was cut off by a 4 year old multiple times while dropping in, only to find them stop at the top of the lip and ski back down. I am so in favor of park passes, just for the safety factor even. Those who want to learn progress and have fun in the park the way it was designed to be will DEFINITELY cough up the extra dough to go in there, those who don't care and have no interest will obviously say out.
Anyone have the link of that video where someone goes to throw a 5 off a jump and tip taps some girls helmet standing in the way?
