Radagast,
Nothing you say about the racism in the system of baseball in the early years of the game is wrong...far from it. Borderline white players would have had their jobs in jeopardy had the leagues been integrated (or perhaps there would have been even more teams as both the pool of players and the pool of fans would have been larger). There were also forms of discrimination in those early years, especially against Native Americans and the Irish (though by no means am I equating them with the discrimination against African-Americans). I think what gets many of us slightly irritated is the reiteration of your argument (which again is more than valid). Most of us agree with your point. Now let's move on ... and find a way to get more African-American young people interested in playing the game of baseball today.

PS You might want to reconsider having Tip O'Neill on your unlimited squad (the one in the league with Petro). I just found this in a book called "A Sporting Chance: Achievements of African-Canadian Athletes".
There are many examples of Canadians in other sports welcoming the opportunity to play against Black athletes, but the white Canadian baseball establishment was either ambivalent or actively opposed. In 1887, James "Tip" O'Neill from Woodstock, Ontario, and the greatest Canadian ballplayer of the 19th century, came down firmly on the side of segregation. He was the ringleader of his St. Louis Browns' teammates in petitioning club owner Chris Von Der Ahe, against playing an exhibition game with the all-black Cuban Giants.
It read, "We the undersigned, do not agree to play against Negroes tomorrow. We will cheerfully play against white people at any time, and think by refusing to play, we are only doing what is right, taking everything into consideration, and the shape the team is in at present."
His attitude was unfortunately typical for Irish immigrants at the time (at least in the US) who found someone lower on the social hierarchy than themselves.
Again, it's hard, without resorting to uchronia or alternative histories, to deny a particularly somber past. Face it we must, but, as I tell my students, we need to use history to try to ask the right questions today so we don't repeat those or similar mistakes.
