Read my post again. I explained exactly how the limited population of males fits the nuhn system developing near the end. It's only extrapolation, not stated lore, but you're only asking for a possible explanation as far as I can tell.
Point is, the males are fewer, not unique or even rare, just uncommon. If they were equal in number to the females, monogamy would be plausible and probably desirable for genetic diversity. With disproportionate numbers, polygamy becomes necessary for survival. Because there's no limit on the number of mates a male could have, they compete to have as many as they can. The male who can attract the most mates gets to father most of the next generation, until another male overthrows him. This series of upheavals continues because it helps avoid close inbreeding as a necessity, and becomes a cultural tradition.
And again, using the word race there doesn't mean the Keepers are a race. It means the trait in question is one that applies to the entire Miqo'te race, and saying Clan, while a touch more grammatically correct, would mislead everyone into thinking it's a trait exclusive to the Keepers. Clarity of intent is more important than absolutely perfect grammar. Since the only possible way to interpret it as you have is by being a stickler for grammar, I can only suggest you loosen up a bit.
