And I say that if you can't take the fact that a phrase which bears little resemblance to its original meaning has been taken over by folks who don't care what the original meaning is and use it in their own way to mean something completely different from its original meaning then drop the use in its archaic meaning and substitute something that does mean what you want it to mean, e.g., 'assuming the consequent' or call it by the Latin petitio principii and baffle those who commit the fallacy.
