The ‘scholar’ is a moron. That is why he speaks such nonsense. It is not permissible to eat with knife and fork. In addition to it being the style of the kuffaar, it is in conflict with the Sunnah, and the Sunnah of licking the fingers and deriving the special thawaab for this act are lost. Only when necessary may one eat with a spoon. The arguments presented for this practice are baseless.
