Enabling people in a minority group to associate with one another while still not excluding them from anything is not segregationist; it's just considerate.

However, you have a very testable hypothesis here with the idea that these policies are the source of the inequality. And much like "Wet ground makes it rain," the hypothesis is easily disproven by considering the order that the correlated things happened in. The ground gets wet after it rains, and these events started being organized in response to the conditions you're suggesting they may have caused.
