You don't get it, not even close. Do you think he denies that there was [animal] sacrifice? (There was very rarely human sacrifice in any but very ancient pagan systems, such as Sumerian and Babylonian) Of course he doesn't, and of course he doesn't deny that they believed in their Gods. You missed everything that was said in that article, it seems. The meaning of paganism is not what the common people "believed in and practiced," but rather which is evident in paganism itself. It is a complex system of values/concepts and spirituality that evolved with the people of Europe, in different forms that all basically were the same in a fundamental manner. The rituals and sacrifices were much more symbolic than anything, they were tradition, culture, a way of showing the people something physical to "connect" them to their "religion" in a clear and evident manner. Obviously the majority of individuals aren't going to understand the full symbolism and poetric truth that was/is deep within the pagan "teachings," but rather the literalistic entwined with the symbolic to maybe simplify it for them. Their faith in the literal deities, though ignorant, made this vital system of values become something "sacred" to the people, something they would die to protect and never forsake. This ensured the survival and thriving of the European people, not the literal beliefs themselves, but what those beleifs made sacred - the deep meaning and value within paganism, the perfection of the system that evolved to work in symbiosis with the European people, gave them a soul as a people, made them truly proud of their sacred heritage & tradition, made them a strong and heroic people built around the values of heroism and vir, of a non-absolute approach to life, one that allowed them to rather than fear the ever-threatening death, enjoy the lives they had to their fullest. It is something too complex for me to fully explain so simply, as this hardly truly touches on it.
