Comment by Galactic Navy Officer on Galactic Navy Officer

@Galactic Navy Officer On a separate note, treating slaves as slaves is a learned behavior, like other forms of prejudice and bigotry. While kids will go "Ewww" at each other for the silliest things sometimes, it doesn't stick long-term unless it's reinforced. 

(This does not include when a child is showing aggressive or vicious behavior and the kids quite rightly want to avoid them.)
