The Americans who know when to use whom and who and Americans who think they know when to use whom and who are those who use whom, while Americans whom the distiction between who and whom thouroughly confuses and Americans to whom whom is entirely unknown are those by whom who is solely used.

Oh it's a bit more complicated than that. There are also those who don't use whom because they know it's a relic of a case system that has been gradually fading for a thousand years. Not to mention those whom use it incorrectly on purpose to annoy the pedants.
