Yes, it is an appeal to emotion but it's also rooted in logic. The "intellectual property" lie is also an appeal to emotion (attempting to falsely piggy back on anti-communist sentiment, even though (c)opywrongs and patents are actually anti-property rights) but not rooted in logic.

> Can you either expand further on your argument

If you program a multi-agent simulation of the world and define slaves and masters you'd have:

    class Person
    class Slave extends Person
      askOnDate(recipient)
       if (this.master.grantsPermission())
         super.askOnDate(recipient)
      sendFile(recipient, file)
       if (file.master.grantsPermission())
         super.sendFile(recipient, file)
    class Master extends Person

Someone who has to ask permission of a 3rd party not involved in a transaction is a partial slave.
