If you look at it this way- Alphas & Omegas are kind of like representative versions of Men & Women of Humankind; even when women in real life are capable of bearing new life, earning a livelihood and sustaining themselves, they are treated inferior to men. Logically it does not make any sense but that's the way it is.

In this AU’s abo dynamics many Yang are also looked down upon unless they’re very upper class, and lower classes ones are often forced into use as studs.
I’ve encountered several fanfics where alpha’s are a minority in the population and thus discriminated against due to the majority of the population not understanding certain ways in which they function— one was a somewhat humorous take via The Avengers.
I never understood discrimination against omegas or in this case yin it doesn't make sense if they are the only things that can give birth to yang shouldn't they be treated 100 times better????? And even if they do release pheromones then shouldn't they be put in a certain holding area it's really aggravating
