This doesn't mean that we don't work to fix our language, but it does mean that we need to be aware of the context a word or phrase exists in and the cultural intersections that go along with it.
We just aren't trying to move someone necessarily "away from an imperfect form" and "toward a perfect form that we decided on fifteen minutes ago." Instead there is a cultural gap, there is a matter of identity, and humanity (and all of nature) likes to defy categorization every chance it gets.
