The Jews were expelled from Spain at the time. So were most Muslims. Usurers were burned at the stake as well. Non-Catholic Christians (in any organized sense excepting a few heretics) were not a factor despite the retroactive hysteria of many of their modern counterparts. Ferdinand and Isabella were establishing Spain as a CATHOLIC nation. We call the concept Christendom. We no longer pursue it anywhere. You could move into Vatican City itself if you could afford it and so desired.
Some small number of people of Jewish ancestry who had been baptized Catholic but continued to practice Judaism (people known as Moranos) were executed by the Spanish state after being judged guilty by the Inquisition. Balancing against such injustice, Spain did more to save Jews from the Nazi Holocaust under Franco than did any other nation. This was because Pius XII urged Franco to use his strategic position on behalf of the Jews in many ways.
Lutherans can point to Dietrich Bonhoeffer as a martyr who willingly returned to Germany to fight Hitler's pogroms and holocaust until Hitler saw him hanged. What did your faith and its adherents DO to save Jews from the Holocaust???? About as much as paleoPaulie would do to keep Iranian boss Ahmanutjob from his intended and announced ambition to nuke Israel. So, please spare us the blatant hypocrisy of whining about matters historical on which many share guilt for following the perspectives of their times. Have you ever heard of the Thirty Years' War? How do you think Jean Cauvin would have treated Catholic priests found at Geneva???
King Philip the Fair of France also barbecued the living flesh of Jacques DeMolay in the 13th century at the request of the pope with no Inquisition involved. Shall we discuss the treatment of St. John Fisher and St. Edmund Campion and so many other Catholic martyrs at the hands of Henry VIII and Lizzy I in England??? Or what happened under Knox and the Presbyterians in Scotland??? Or the confiscation of the Catholic Churches in Ireland???? AND, it is true that the Catholics barbequed Wycliffe and Hus.
Clearly none of this sort of thing comports with American traditions of religious freedom for which the mostly Protestant founding fathers were responsible (at least nationally) and rightfully get credit. Don't kid yourself that their actions had half as much to do with fear of Rome as they had to do with a rejection of Church of England style persecution of other religions. Catholics have thrived here as a somewhat unintended consequence and ought be grateful accordingly.
What we don't really have to do is remain silent in the face of selective history applied by bigots with an agenda who have shown their colors. Your bigotry is not attributable to your faith and it would be unfair and bigoted for anyone to suggest a collective guilt of people of your faith. This is your perversion and not theirs.
As to the general question of treatment of Jews, your candidate advocates stnding idly by while they are incinerated in Israel and no candidate who will EVER get my vote will join paleoPaulie the cowardly pipsqueak in his blase attitude about anti-Semitic genocide by Islamofascisti.
BTW, you should look up auto da fe. You clearly don't understand what that was either.
Finally, let me buy you a clue on the use of the TdTGC. It came into being in response to INTERNAL schism of some formerly Catholic folk who had been declared schismatic and excommunicated by John Paul II. THe schismatics are the SSPX. Whether you personally were born to a family not Catholic or whether you apostasized to leave Catholicism, the title of TdTGC is not aimed at folks, like you, at least honest enough NOT to claim to be Catholic while simultaneously trying to attack the Roman Catholic Church from "within."
Your religion is your business. My religion is mine.
So the issue remains: Did paleoPaulie and his buddies barbeque our country at the quisling's birthday bash???
