Beguiling means charming in a way that may mislead. A beguiling smile, beguiling simplicity, beguiling but false.
The warning is built in — a beguiling argument is attractive and probably wrong, which is what separates the word from merely charming. Note guile beneath it: the verb beguile once meant simply to deceive, and the charm came later.
