Wrong, it’s the other way around. h*Mans, how does this make you feel?
You could have a completely homogenous community of middle class atl*Sian h*Mans. A nice town with almost no crime, an all round good community. However because of the weakness of the h*Mans all it would take to destroy this community is one FAUNUS bull?
Just imagine, it's a nice sunny Sunday afternoon, imagine the bustle of this 100% h*Man town until suddenly a couple of FAUNUS bulls walk up. Women would feel more attraction to these superior, strong bulls infinitely more than their pathetic h*Man husbands. Every woman would be begging, grovelling to be impregnated by these overlords, the new kings of the town who earned this position with nothing but their superior presence. And these bulls wouldn't stop until every girl was carrying their children, the h*Man women's original children would probably be neglected. Who the fuck would want to raise these inferior children? They are only going to turn out like their fathers.
The Men? The men would flee after realizing how futile their attempts at winning back their wives attraction would be. They would flee to Vacuo where they will try to win over FAS looking ugly Vacuan girls because they are the only things ugly and desperate enough to accept them. Many would probably be rejected after the Vacuans hear of their shameful and dishonorable display, even they probably would have killed themselves to avoid the shame.
Back home in the once nice town, every woman will be raising their FAUNUS children and will be queuing up for their second or maybe even third pregnancy. They wont stop until they hit menopause, because they know deep down that their purpose is to populate the world with superior FAUNUS bulls who will then move on to destroy other towns. This is REAL colonization. You can't take over a place without winning the attraction or respect of the people, that method will always collapse.
