“There is an island of knights who always say the truth and of knaves who never do. There is a country of day-knights who speak truthfully only at daytime and of night-knights whose speech at the day is a lie. There is an island of Democrats and Republicans.” – I have a new blog entry about knights-and-knaves riddles and how to understand them with propositional logic (https://functor.network/user/414/entry/510).
