Answer:
Segregation teaches the very word of hate. By separating colored people from white people they are showing society that one is not like the other. That one is lesser and the other better. This also teaches prejudice because when you can have no contact with the other race you let others tell you how they act, speak, and even what they think when it may not be true. Leaving you to draw conclusions about colored folks without even knowing them. Like with Prejudice, it spreads the idea of racism forward. Separating people will never make them colser together, never let them understand each other and builds more hate.
Step-by-step explanation:
"Separate but equal, is never really equal."
