No subgroup, race, nationalism, religious group, gender based groups or other identity essence based groups will never be more important that, and should never ethically take presidence over the existence based universal group, the human group. Universal identity takes precedence over subgroup identity, and when we are forced to subgroup in reaction to injustice, that is the only ethical subgroup.

Survive in such a way that you avoid limiting others who are also trying to survive. We all live in limited systems. This is the core of ethics.
