It was never a safe haven

You are absolutely correct… I just read about the horrible massacres Muslim carried out against Jewish people in Jerusalem in 1099. Here's an eyewitness speaking of it…

"…[our men] were killing and slaying even to the Temple of Solomon, where the slaughter was so great that our men waded in blood up to their ankles…"

Oh. Sorry. My bad. That wasn't Muslims. That was (supposedly) "Christian" Crusaders.
