The “problem” with the “slavery is bad” point of view is that we talk about MACHINES. AKA tools. My computer doesn’t have human rights. My fridge doesn’t have human rights. The coffee machine which created the coffee I am drinking right now is not my SLAVE, it’s a tool which was created for making my life slightly easier.
Well there’s a big difference between R2 and your coffee machine. That being said, everyone disagrees that droids should have rights except L3. The characters around here are just as annoyed as we, it’s not a political message. Do you really think Disney is pushing for iPhones rights?
