Sorry, but we're clearly both. There's a whole lot that's left out, sure, and I'm pretty sure Locke was being somewhat facetious. But, yeah, to be just a sex object is to be marginalized - dangerous and discriminatory.
Objectification is misleading when it causes undue attention on the irrelevant.
It can be discriminatory. I think most of them hated the term. Thankfully, now we just have engineers again. The mere addition of an adjective affects one's perception. So yes, we are all sex objects.
