This is well-reasoned and accurate, but objectification isn’t just about sex.
From Wikipedia (https://en.wikipedia.org/wiki/Objectification):
"According to the philosopher Martha Nussbaum, a person is objectified if one or more of the following properties are applied to them:
Instrumentality – treating the person as a tool for another’s purposes
Denial of autonomy – treating the person as lacking in autonomy or self-determination
Inertness – treating the person as lacking in agency or activity
Fungibility – treating the person as interchangeable with (other) objects
Violability – treating the person as lacking in boundary integrity and violable, “as something that it is permissible to break up, smash, break into.”
Ownership – treating the person as though they can be owned, bought, or sold
Denial of subjectivity – treating the person as though there is no need for concern for their experiences or feelings
Nussbaum has argued that the topic of objectification is not only important to sexuality, which has been discussed at length, but to the Marxist view on capitalism and slavery."
Let’s take this picture:
This image is not inherently sexual, yet it certainly meets Nussbaum’s definition of objectification. I guess what I’m saying is that while we most often talk about objectification in sexual terms, it is a much broader topic.
