So what would you have the Vissians do? You're quite willing to criticize them, but what's your solution to their problem?
I already said what the Vissians should do.
1. Name cogenitors, like any other people.
2. Allow them basic human rights, like education and opportunities for leisure.
3. Treat them with dignity. Are you and your wife getting ice cream sundaes? Give one to the cogenitor as well.
Yes, they have to go from family to family. No, they can't have as much of a part in their children's lives as moms and dads. That is the nature of the species, just as women used to have to raise their kids because they were the food supply. But there was NO REASON why the Vissians couldn't do what I just suggested.
