They aren't animals. They have brains and choices. They choose to come here, work these jobs, and often refuse to assimilate while doing so. Being a pawn doesn't absolve them of anything as all those are things they directly made the decision to do, they weren't kidnapped off the Savannah and brought here in chains.

And if you think they are mindless animals, then we should be skipping all this theater and just putting them down like we do with overpopulated animals.
