Two different timing situations. Weren't Germany and Italy Christian states just before going into fascism? Was there a time from 400-1976 when Italy was not Catholic with the church reviewing laws and Catholic teachings codified in civil law?
Your response totally misses the point. The entire western world - including those who opposed the fascists - were Christians, and Ron Paul was responding to Huckabee candidacy as a Christian.
Neither Hitler or Mussolini ran or governed as Christians and they were both anti-Christian. In fact, Mussolini as a child was not baptized but banned from church for throwing stones at the congregation and was often opposed by the Vatican as a ruler. Hilter disdained Christianity and often spoken of his admiration for Islam. (I can provide citations.)
