Greetings,
Many inquisitors and conquistadors were Yehuborim themselves. So long as the higher-up Yehuborim held power, persecuting less powerful Yehuborim was not a problem. The same happened under the Stalinist Soviet Union. Many say Stalin was "anti-semitic", but he was the first leader who recognised Israel.
Christian anti-judaism only reinforces the Yehuborim spiritual stranglehold over the Gentiles.
