The thread only turned to the question of the Inquisition because you brought up the reason for the spitting is that Catholics burned Jews at the stake in order to convert them to Catholicism. Do not make a charge if you do not want to listen to defenses against it.
More like burned them at the stake for failing to convert to Catholicism. Obviously a minor point difference between us, but a rather serious issue for the poor guy on the stake I bet. Now the survivors would be the point of this issue, as the person on the spit, does not spit on a person. But the survivor would remember for a while that dad was burned alive by Catholics for being a Jew. And perhaps would want to spit on one if they walked by in your holy city. But if you think that someone who had a family member burned alive apon being told they were burned not because they were jewish, but because they were catholic jews would go, "O thats OK then, sorry, go ahead burn my dad alive..." Well, then we have nothing further to discuss.
