100% a matter of who the particular official happens to be. When I worked baseball and football there were guys who would let about anything slide, and there were guys who'd throw a flag or eject someone at the drop of a hat. It's an art because if an official
When it comes to pure judgement calls like that it's purely interpretive and everyone has their own "threshold."
My personal umpiring thresholds...
1) Coaches arguing is fine as long as you aren't calling me a dickhead or something, call time out and come talk to me and I'll tell you what I saw. I know from coaching myself how pissed off you can get and I'm fine letting people vent but when we part ways it has to be done.
2) Players arguing balls/strikes is a no go. If it gets to be a thing I talk to the coach quick between innings and I never had it get too bad after that. I shouldn't say this but the player arguing thing tends to be directly correlated with the "demographic" (read, income level) of the school if you catch my drift. Private school kids who drive brand new vehicles and dad's a mid six figures guy tend to be much smarter than me and more entitled than joe blow public school kids who've been told no before by their parents...but I digress, lol.
3) Stuff that's directed at players/coaches/dugouts is pretty much zero tolerance. There's no penalties in baseball so you pretty much have to toss the kid. I wish in high school you could add an out or take a run away or something but you can't.
Dumbest one I ever saw was School A was really good and School B wasn't but School B was hanging tough later in the game down by like one run or whatever. School A's stud hitter was at bat and with the kid behind him it was an OBVIOUS intentional walk situation. Obvious as in I knew it was coming before they even said anything. School B did the right thing and put him on, and as soon as their coach told me to walk him the batter asked if he could refuse it...I said no and he proceeds to sidestep all the way down the first base line directly facing the dugout at like half walking speed locking eyes with the coach the whole way down.
