What was Jackie Robinson act of courage?

Answer 1

Jackie Robinson was the first African-American man to play baseball. The major league was fairly new at the non-segregating game, and most African-American men were afraid of the white men already in the major leagues making fun of them for the color of their skin.

Jackie Robinson was not fazed by this and as a result, started to play in the Major League. This brought spitting, ridicule, etc. from his teammates because he was black, and Robinson kept going with it, encouraging other blacks to join the major leagues.
