Why is objectifying people considered a bad thing?

[Alexander]

to use a hyperbole so that your peanut brain can process it - for the same reason slavery is morally unacceptable

you are laughably bad at this

an object is not necessarily property

an object is considered as having less moral value than human. to label a human with such a name implies that they are of lower moral value. like calling a human an animal. or calling a human a 'clump of atoms' and so on.  it is dehumanising to call someone by something that is of lower moral value. it ignores their humanity

wtf is moral value you are just making terms up and being human supremacist

who gets treated better human supremacist or human hater? do you not get what I am saying?
