Whitney Curtis/Reuters Christian traditionalists are filled with pessimism as they watch the rapid spread of same-sex marriage. The most thoughtful harbor no animus toward gays and lesbians. Chris Roberts, a Catholic theologian in Philadelphia, says that while he would decline to bake a cake for the wedding of a longtime gay couple with whom he had a friendly relationship, he would gladly bake one for a birthday party or funeral "to honor their friendship, loyalty and faithful service to each other over years." Ross Douthat declares that, if asked, he'd bring the cake to a party he's attending to celebrate the same-sex marriage of a longtime friend, "but I would be uncomfortable attending same-sex vows in the style of a Catholic Mass." Seeing all opposition to gay marriage cast as irrational bigotry, likened to segregation, and even analogized to the Ku Klux Klan is understandably dispiriting for them.
