I absolutely agree with you although I’m not sure its strictly paganism. A pagan was how Christians defined those who still worshipped the gods of ancient Rome and Greece and variations of the practice are found all over the world.
However, a Melanesian warrior from Borneo today would instantly recognize the belief in (ritual) cannibalism as a way of absorbing the power or spirit of the Other. Cannibalism has never been explained by its primitive native practitioners as a palliative for hunger or protein, but rather as a spiritual joining.

You don’t understand the first tiny thing about the Sacrament of the Eucharist. You don’t have the faintest scintilla of a clue that would be large enough for a scanning electron microscope to detect.
You congratulate yourself on your superiority to those who do understand, but in fact you wallow in misprision and disinformation. Ignorance would be a step in the right direction for you.
