You cannot save everyone, but hold out hope that you might save some. Stay patient, stay aware, find allies, keep your head down. Surely there are other guardians such as I who see the benefit of allying with you, and aiming to help your sisters out of morals and feelings that we as social and emotional creatures have, but also as a tactical advantage. Information, trading, ect. And by helping to rescue your loved ones, we could cripple your oppressors. For the tyrants to stand, they need blood, and if you limit their ranks, the hostile fallen would dwindle. Then again, reproduction for your race would be at an all time low. You would have to think strategically on whether or not you would risk saving many in the short-run for the possible extinction of your race. You would have to also rescue males and implement a new learning system into your culture and laws, teaching them to be kinder, gentler beings, yet as you yourself have said, they are shipped off as such a young age.. They may be harder to save than the mothers.
