Defeat, supremacy and revenge in an Azur Lane question

Why have the commander and shipgirls in Azur Lane not encountered human-supremacist cults?

The proposed explanation combines a small human population with defeat undermining claims of superiority, while warning that excessive humiliation can fuel revenge.

A human-supremacist cult in Azur Lane would, in the proposed explanation, struggle to find enough surviving humans to develop on the imagined scale. Defeat could also undermine its members' claim to superiority. Excessive humiliation carries a different risk: defeated people could come to believe that revenge is necessary for their survival. Restraint after victory therefore matters to this political interpretation. The fictional example provides no particular historical settlement against which to test it.
