Before I was a leftist I felt this way about romantic relationships as well. I’d listen to other guys objectify their own s.o.'s and I’d think “how can I love someone and objectify them?” As a leftist I love everyone and they are all valuable and developing. How can I love someone and objectify them?

There is actually an interesting philosophical notion (I think Hegel - edit: yes Hegel’s Master-slave dialectic) which describes interpersonal relationships as being guided by the subject-object dynamic. The desire of every human is to be seen as a subject (acknowledging sentience), not an object (denying sentience). And in some dysfunctional people this manifests itself as reducing others to objects, which forces the others to view them as the subject. Slavery, sexism, racism. In well adjusted people this manifests itself as a desire that all humans should be seen as subjects and should see themselves as such. In fact I believe the key tool of reactionaries is to present the proletariat with a false choice. That is: you are human or they are, when the truth is that we can all be human and live well if we remove the parasitic landlord class.

That is why I love this quote from Che “At the risk of seeming ridiculous, let me say that the true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality.”
