Right. In order for Emma to break up with Hook, the first thing that needs to happen is for the two guys writing and running this show to be aware that what they are writing is abusive but since they don’t, they won’t. It’s a standard, “if then” clause. If A happens, then B will occur. But since A isn’t going to happen then B won’t.
And to step outside CS, the same can be said for all the other host of issues that plague OUAT at large (or, heck, take it further–that plague network TV at large). Like rape culture in media, sexism, classism, elitism, racism, homophobia, transphobia, and paranoia over anything that can be “otherized.” This is an OUAT forum so we stick with that show for the most part (obviously) but, to be slightly fair, the larger cultural problems that we bring up as problematic to OUAT are not localized solely and exclusively to OUAT.
