Let's begin to confront this one head on:

Summary: Research shows that people like those who are similar to them.
Moreover, the more heritable a trait is the more important similarity in
it is to friends and spouses. Thus, people enjoy the company of those
who are genetically similar to them. This may explain why people to
marry, befriend, and live near, members of their own race for more than
randomness would predict. Moreover, a rich literature of correlational,
longitudinal, and experimental, data shows that people get along better
with members of their own race and that ethnic diversity damages social
cohesion.

...

The experimental evidence is pretty straightforward:
researchers measure
various traits of individuals before they meet and then see whether pre
meeting similarity predict who ends up liking who. The finding, repeated
over dozens of studies, is that the more similar people are the more
they end up liking each-other (Bryne, 1971; NewComb, 1961; Lee, 1996;
Myers, 2008 pg 400

).

...
In conclusion, the totality of evidence clearly shows that ethnic
diversity damages how well people get along, how much they trust one
another, and how satisfied they are with their lives. These findings
should be kept in mind when thinking about any form of racial diversity,
regardless of the races involved.
