People are used to idioms they don't understand though. They're much like words in that we learn their meaning from context, and the etymological content is more of a subconscious mnemonic than something we explicitly pay attention to. Sort of like being surprised when you first notice that "disintegrate" is "dis- integrate". This is particularly common with idioms because they often to get truncated over time so that their meaning is harder to extract from the content. If you've never heard "the pot calling the kettle black", but you've heard "pot: meet kettle", you'll likely get the meaning from context, and you'll have no idea what the connection is between hypocrisy, pots, and kettles.
