Probably because the omega or alpha is all secondary gender, and primary is male/female.
There are non-omegas, betas, or some donβt have any secondary gender at all and have a non-same sex relationship (in some omegaverse) so probably those are the ones discriminating.
Itβs possible to still be attracted to the opposite primary gender and discriminate the same primary sex.
Homophobic omegaverse is so illogical to me. If men can give birth then the traditional arguments against homosexuality don't apply, why is having a male partner seen as not so desirable still
