Anti-semitism is based on an irrational hatred and is unlikely to change due to a reasonable argument. However it can change as the person with the hatred changes.

The deny that Jesus was killed to satisfy a segment of Jews is the equivalent of sticking one's head in the sand. First century Jews killed people they believed to be offensive. Stoning was the usual method. Since the Sanhedrin wanted Jesus to suffer a more severe and painful execution they enlisted the aid of the Roman government. Does that mean that every person of Jewish ancestry forever more should be held responsible. NO!!! Christians have also killed people they considered to be dangerous and included Bible translators among the offenders. Does that mean all Christians forevermore are to be held responsible? No. But Christians should be vigilant and not permit that to happen again.

And I repeat, "holy people" was used purposefully by Sydney Carter to describe the irony of so-called holy people acting in a most unholy way. The phrase was meant to offend those who live under the pretense they are something they are not. It is not meant as anti-semetic. I did not know Sydney Carter personally, but do find him an intriguing person and wonderful writer so I have read a bit about him. His system of belief and un-belief was such that he had the utmost respect for Judaism and those who practice that faith. One of his closest friends was a Rabbi.
