Ambiguity is one of those things that just keeps and keeps growing. As the world evolves new meanings are attached to existing words, because the reality we live in keeps changing. the word swamp means something new now, as it is being drained to make people's lives better again.
But frankly, I wish they'd hurry up, although I also wish what we've been told was never actually true. If only no children were hurt in this movie, the world would be a far better place.
