I do consider maximum integration ideal. The more you segregate people, the easier it is to start wars and other violent conflict. Many Americans have no problem with bombing (or droning) Iraqis, for example. There would be more outrage if you droned black people in Baltimore. But even in Baltimore the segregation causes problems. It's just human nature, to create in-groups and have special morality for them, and modern societies should fight it, by intermixing people. Democracy and social equality are good instruments to do so. Ideally on planetary scale, but were not there yet. It can also be seen as a tradeoff. With segregation, you get a more closely knit community in the inside, but less to the outside. Conflicts occur in both scenarios, but there are different ways to dissipate it. Interacting with people you don't know that well dissipates the conflict often and by very little, which may be frustrating and lead to less happiness. Closer-knit community may dissipate conflict to the outside at once, with violent results. So it's really choose your poison situation - be perpetually unhappy in individualism or be happier now but risk a larger war from time to time.
