Anti Semites hate him because he readmited Jews to England so he must be a good person
Not necessarily true. Many world leaders have, for a time, pretended to be philo-Semitic because they needed Jewish help and cooperation on something (i.e. their scientific, administrative, or economic skills) for their s**thole stone-age countries. A good example would be King Casimir of Poland, Joseph Stalin (who helped the Ben Gurion regime briefly, because he thought Israel would become a hardcore Marxist Soviet vassal state) or some of the Muslim Nazi beasts who ruled the Ottoman or Moorish empire in the Middle Ages (who granted the Jews certain rights, in exchange for their services).
