Is it obligatory to condemn someone who eats or drinks with their left hand, and is taking and giving with the right hand a Sunnah or an obligation?

Scholars have differed regarding the ruling on eating with the right hand: is it obligatory or sunnah? It was previously chosen that it is among the Islamic etiquettes for which one is rewarded for observing, but not punished for abandoning. Similarly, taking and giving things with the right hand is not obligatory according to the majority of scholars. One who abandons sunan (plural of sunnah) and Islamic etiquettes is not to be denounced; rather, his advice is to be sought Islamically.
