Catholics Worship the Eucharist

So catholics worship the eucharist. Would you say this as a form of idolatry? How would you, as a protestant, approach the morality of this? So i'm im un clear how it would be a form of Idolatry. It's no less idolatrous than worshipping something and thinking it's a different god. When moses was up the mountain and they collected their earrings and gold and put it together, they said, this is your god who led you out of egypt. The same argument could be made there. But i think it still, i think Catholics would be not just idolaters, but the most stupid of the idol
