Define “Catholic Hispanics” and “Protestant Hispanics.”
If you mean those who immigrated from anti-clerical Latin-American nations, regardless of religious affinity compared to those who are enculturated into and remain enculturated into Southern-style, white-led evangelical Christianity, you are correct.
If you mean those who were significantly catechized and participate routinely in the sacraments, compared to those who reject the authority of the Catholic church based on Protestant rationales, you are wrong.
Much of Latin America is very poorly catechized: Priest-to-Congregant ratios are less than one-fifth the European model, and frequently less than one-tenth. The nations are called “Catholic” because they were simply officially declared so, and the peoples baptized without true conversion or even evangelization. US-funded anti-clerical regimes typically placed great difficulties on providing adequate priests; the US-backed Mexican Revolution led to the deaths of 20,000 Mexican priests, nuns and Catechists. Those who emigrate to the United States often represent the poorest catechized, and those from the weakest family backgrounds (otherwise they wouldn’t leave their families and communities behind to break our laws).
Many non-Christian churches have had great success among the poorly catechized of Brazil and other cultures. These churches are typically called “Protestant,” “Evangelical” or “Pentecostalist” by triumphantist Protestants, evangelicals or Pentacostalist, but frequently involve paganism, worshipping of demons, or anti-Christ-like cult leaders. In many cases, the adherents quit Catholicism precisely because during the Post-Vatican evangelization of Latin America, the church leaders finally had the personnel to impose a rejection of syncretic and superstitious faiths.
(Many Protestants characterize such superstitions as if they were part of teh Catholic Church. In fact, they are pre-Christian traditions which persisted because the Catholic Church lacked the missionaries to convert people away from them.)
For these reasons, I’d been posting here and on other fora not to be surprised if the recent elections did not result in a South-American priest; the pool of candidates to be pope (that is, priests) is much smaller (26%) than the overall population (58%).
Catholic Hispanics will never become as conservative and pro-life as Protestant Hispanics, but every little bit helps.
Pro-lifers may never win the Catholic vote again as it is so supportive of the democrat party, but it is possible that it could happen once or twice more.
