Unregulated slavery is a taint upon mankind. It is good to see some independent pilots, misguided as they may be in their choice of allegiance, recognize that the Federation is suffering from lack of regulations regarding slaves. If only your leaders had half a brain, they would understand that the Imperial way is truly superior.
Slavery, even if dressed in finery, is still slavery. The Empire speaks of slavery like it is some great and noble service. You can candy coat a turd but once you've licked off the sugar you're still left with a turd. Slavery in the Empire still denies that mankind has a basic right to liberty. It's "place of honor" in the Empire is not about what is good or what is right. Its about assuaging the guilt that the rich and powerful should rightfully feel about this horrible practice.
