Is Catholicism Pagan Rome?

Over the years I have come across a number of Protestants, many of which were Catholics, claim that Catholicism is pagan.  They often use the same claims Zeitgeist uses to "refute" all of Christianity, even Protestantism. The tactic these people use is essentially filter out all of the information that would be perceived from their view point to be antiChristian, and only allow in information that are uniquely against Catholicism.  One of their claims is about the Virgin Mary, they claim the Catholic representation of her is pagan. The book they sourced was From Bethlehem to Calvary: Initiations of Jesus by Alice Bailey--a book rewritten to "refute" the New Testament. What the antiCatholic ignored is that it calls the description of the woman in Revelation 12....pagan.
