The fans may be a different story.
That is a true statement, at least fron what I’ve observed.
Only Golf exceeds Baseball as a civilized sport. But yes, the fans can present a different story. I recall one or two times when somebody got beat up after a San Francisco Giants game. This one fellow got attacked in the parking lot by two guts wearing the colors of the losing team. He was in a coma for weeks. Still alive, but can’t work outside the home anymore.
Someone once told me that, of the four major pro sports, baseball players are the most conservative (on average, of course), followed closely by hockey. Football and basketball are on the far opposite side of the political spectrum.
“Baseball is generally the tamest and most well behaved of all major sports...”
Hockey aside.....you need me to tell you why that is?
I'd say it's Cricket unless you're limiting your observation to the U.S.
Volleyball has the most tamest and well-behaved teams and fans.
