Actually, baseball did more to attack racism than the Congress, the Senate and House, and the Supreme Court when the Dodgers integrated in 1947, one year before President Truman integrated the armed services. Indeed, one could well argue that one led to the other and that MLB and baseball writ large have done a better job of integrating and mitigating racism then has the government and/or the armed services.
Violence and racism were/are endemic to American society.
And one could fairly say that arguing with umpires was therapeutic for managers, players, and fans alike. Those arguments were time-consuming, but sixty and more years ago they still played games quickly (compared to today).
