From George Weigel on why protecting marriage through the FMA is so very important.
5. The same charge of bigotry will be laid against priests, ministers, and rabbis who decline to perform "gay marriages." One young priest I know, an entirely sober soul, told me that he fully expects to see clergy of his generation jailed for refusing to perform same-sex "weddings." He is not being alarmist. Unhappy precedents have already been set in Canada and Great Britain, where clergy have been subjected to the pressures of the criminal law for teaching classic Christian doctrine on homosexual behavior.
