Query: Has some real facts but is biased

I have done research into this topic and have found that Cahill did supply the reader with some real facts. Unfortunately, he also came from a biased christian standpoint. Cahill made the celtic pagan Irish seem that they were a lower level of people in thier religion and that they needed to be "saved" by the new religion of christianity. He also goes on to say that they desired this saving in their subconscious mind. Of course, there is no evidence to support this statement. For someone trying to get a pure historical factual based recount of Irish history, this is not it.
