Gerrold, who is scheduled to emcee the upcoming Hugo award ceremony, has previously written that Mormons are "in league with the Catholics and the Confederate Party." He also wrote, "The Catholic church only gets to decide what Catholics may believe or how Catholics should behave... If you're going to call yourselves Christian, then follow the teachings of Christ or ... shut the f**k up."
ADDENDUM: Gerrold has claimed that every Catholic priest he ever met is a pedophile, together with the following remark, "I recognize that anecdata is not empirical evidence. But still..."
Apparently that's acceptable to the Hugo awards committee.
Tip of the hat to Anonymous.
