Confucious and Yenta raise the canard that Koch was a homosexual. As far as I know, the only evidence for this is that he never married. When he was running in the Democratic primary for governor, some people used the slogan “Vote for Cuomo, not the homo.” Mario Cuomo distanced himself from this slogan.
As far as I know, cemetery plots are available in Jewish cemeteries in the outer boroughs. Koch’s wish to buried in Manhattan could be interpreted as a slap in the face for the other boroughs.
