Many of the Jews that were forced to leave Spain had previously (for their safety and security) converted to Christianity. Many knew quite a bit about how to pose as a Christian and probably even more knew how to keep their mouths shut. Perhaps it was during such trying times that the old saying, “don’t ever argue religion or politics”, became popular. For a Jew residing in a medieval Christian kingdom ... good advice.
