Not to say it hasn't happened, but I don't ever remember seeing anyone get kicked out of a tournament for properly questioning an official's call. Everyone I've ever seen tossed was being a total jack. For every person I've seen wrongfully ejected, 50 more should have been IMO. To me, this is the sport of the highest honor and it is different. You do not see high school wrestling coaches act like high school basketball coaches. The rules do not tolerate it--same with college.
Clearly youth officials are human and make mistakes, but they are in about the worst situation of any official in any sport. The volume of matches and proximity and intensity of the spectators along with the noise and overall stress of the youth tournaments can make for a hostile environment. Many of the coaches and fans are passionate, but not that knowledgeable about the rules they are arguing. I'm sure that gets old. I know it does for me as a coach.
