I think that there is a history of anti-Catholic bias throughout history. This can be seen in the "supposed" founding of Catholicism by Constantine, the Great Schism in 1054, the Crusades, the Inquisition, the Protestant revolt, WWII, and the way the Church has been treated in recent years. All groups paint the Church as the bad guy but they fail to look at history for what it actually says and the say what they what it to say.
