Up until S4 of ENT, the common belief was that the Orions were a very male dominated species, whilst the females were seen as slaves or 'animal women'. In ENT we even got to see an Orion Slave Market, where a female was sold. A few episodes later its 'revealed' that actually its the women who are in charge, controlling men with their pheromones. If thats the case, why do they allow themselves to be sold and why are they so prized a century later, if the 'owner' will actually be under their control? Add to this the fact that the Orion Syndicate appears to be the name of their government/empire/territory. I always thought the the Syndicate was more like a large criminal organisation, as when it was on DS9, there wasn't an Orion to be seen.
