The REds in those days had Rose and Bench and then Morgan to help enforce it. HOF superstars that were as big as the game.
The Reds in those days had parents that grew up in a different era, in the depression and during jim crow.
Different eras makes different people and a different value system to teach their kids.
Today's Reds grew up in post war suburbia with cable TV and a "Free to be You Free to be Me" soundtrack pounding through pop culture.
