How is modern philosophy more anti-semetic then the Inquistion?
It has to do with origins, purposes and ends.
At its worst, Ferdinand and Isabella required the Jews to either convert or leave their realm. Much of the justification of this was the idea that Jews living side-by-side with “conversos”, converts to Christianity, would lead the latter to stray from their new faith.
But to these modern philosophies, conversion or expulsion wasn’t enough. Jews had to be annihilated, as they believed in God, not the state, as supreme being. This is seen across the spectrum of philosophies. The state must destroy God to become the new god.
And this was not limited to just Jews.
