If you want DH5-DH6, my advice is: stay away from metaphors! People will react to your metaphor first ("so-and-so is dead", "so-and-so is a lion in a cage" etc)

If you want DH5-DH6, my advice is: stay away from metaphors! People will react to your metaphor first ("so-and-so is dead", "so-and-so is a lion in a cage" etc) instead of your main thesis. Metaphors aren't "isomorphisms", sorry. They make things more colorful but can't be refuted rationally.
