Immigration powers Democracy's envy engine, and the point of Fascism's gender skew is to uphold egalitarianism. Only an idiot wouldn't have figured this out sooner.
The iron law of oligarchy is true, and democracies are run by an elite oligarchy. Typically a top-out-of-sight oligarchy whose names never show up in the news. Indeed becoming visible, especially in such a gauche way, results in their rivals ganging up on them and casting them out of the inner circle.
It is hard to see how this oligarchy benefits from immigration. Cheap labour? What, you pay for your own workers? What a rube. Sheer Impact, making the peasants unhappy? Too weak. They work diligently in pursuit of greater immigration. Votes? Err, iron law of oligarchy, my dude.
But, duh, democracy is an envy engine. It is founded on envy of the elites and continues to function on the envy of the lower classes for the middle classes. Thus, a strong democracy has the largest possible lower class. Hence, the idea is to import as many partial failures as possible. Import those who envy the natives, and create a vigorous, healthy envy cycle.
The constant talk about racism is there to intensify the envy. Nobody claims that being good at written school tests isn't important. They instead constantly throw the difference in test scores in the lower classes' faces. They get away with this by pretending that they're condemning some poor scapegoat for causing it. Standard Fascism point 3.
The votes and impact are nice bonuses, though. Why satisfy one goal when you can go 3-for-1?
Speaking of Fascism, I said, "The gender skew is plain weird." It's not, of course. Fascism is fundamentally fundamentalist egalitarian theocracy.
Egalitarianism doesn't work, and that's the point. Nobody is stupid enough to genuinely believe that men and women aren't different. Egalitarianism is all about throwing those differences in everyone's faces by bringing them up all the time, but pretending that they're caused by malign actors instead of caused by impersonal reality. (Firing the envy engine and distracting the peasants from Fascism's failures.) Only a bad person wouldn't believe in egalitarianism, and thus everyone pretends as hard as they can.
Naturally this means pretending men are women or pretending women are men. Hence, masculine or feminine Fascism. Women/men are only allowed to be part of the clerisy/government if they can convincingly pretend to be men/women.
It's not easy; to make it easier, the voters are encouraged to be as androgynous as possible. Sin is in all of us, and we must fight it daily, lest we fall. Having a man acting all manly next to a female governor would throw her inability to be masculine into sharp relief. The peasants might have inegalitarian thoughts. Heresy! No leading the flock astray!
