What you think Maniac meant when he said " The less they know about each other , the more they invent."?

In this quote, Jeffery thinks emphatically about how segregation perpetuates racism. He sees that many people that he likes do not like or understand people of other races because they assume they will be different from themselves, when truly they are much more similar than they would think. Jeffery thinks back on the homes he has attempted to create with welcoming families both black and white and the chance he has had to see issues of race from both sides. This passage suggests that more interaction between races would go far to diminish racism, perhaps especially in Northern, urban areas.
