Almost-incest is a recurring plot in TV shows such as The O.C. (Shannon and Ben), The Flash (Barry and Iris) and of course Riverdale (Betty and Jughead). Some disgusting people have been trying to justify and normalise this, nevertheless, encourage it, and as the writers of these and many other TV shows have failed to acknowledge and/or speak up of the wrong in this, it has been in many shows for many years and has developed the term "almost-incest"
Almost-incest should stop being normalised in TV.
