You're thinking about it from the wrong direction, although that may be due to poor wording on my part in my other comment. I meant the groups the labels applied to, not the ones being called those labels. If said groups didn't exist anymore, neither would the labels.

Remember, in a other story Harley goes along with killing the unborn child of Superman and it leads to the Injustice universe, she's that insane nobody wild be off limits to her when written by someone not using the character as a self insert.
