And nice try at snarkiness, but somewhat inadequate. As my dear old dad says, if you can't tell me to pack my toothbrush and go with the sheriff, it doesn't really matter. My Martindale's an AV, if that means anything to you.
The French mathematician/philosopher Jules Henri Poincaré once wrote that “to doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection.” This is the principle you violate here. If you discount an entire work because of a single misspelling or error in grammar you are acting foolishly. To “doubt everything” in the piece because of a single misspelled word is not very smart.
