Sportsmanship? That was always something for rich people in Country Clubs that had to do business with each other on Monday.
Baseball is a sport that started out for the hard scrabble people. It has always been an iffy affair. Hard drinking, stealing signs, watering fields, spiking and dugout "chatter". The stands were worse if you don't believe me go to a Yanks/Red Sox game sometime if you want to see unhinged "people" who are closer to animals let out of their cage than anything else. It might be getting better now that ticket prices have soared in recent years.
Ty Cobb starting riots, Chapman screaming unspeakable things at Jackie Robinson, head hunting from the mound are some of things old timers whistfully recall as they grumble about the growing softness of America and the future.
Hell blowing up defenseless middle infielders and catchers and destroying careers was "old fashioned hardball" until about 24 months ago.
Baseball like everything else evolves to new "norms" and as far as the violence on the field and the type of acceptable noise in the stands ….it is becoming more civil and not less than it ever was before.
The availability of personal information is a new wrinkle. There is a part of me that subscribes to the notion that you shouldn't broadcast your life if you don't want people to know and use that information against you. In some regard you get what you deserve. But that is another topic entirely.
FWIW ….I am in favor of the cleaner approach. Players should be able to walk when they are done....and a little perspective on the importance of a HS game much less any higher level game is in order IMO.
As someone in the stands, this simple question should be asked "How does your team winning make you a better human being?" The answer is that it does not....and never can. Enjoy the games...like you should.
