ATB's uncredited quote is from Chief Justice John Roberts' dissent.
Hard questions arise when people of faith exercise religion in ways that may be seen to conflict with the new right to same-sex marriage—when, for example, a religious college provides married student housing only to opposite-sex married couples, or a religious adoption agency declines to place children with same-sex married couples… Unfortunately, people of faith can take no comfort in the treatment they receive from the majority today.
The questions aren't that hard: Bob Jones University v. United States
set a clear precedent that religious universities enforcing racially discriminatory policies based on "biblical interpretation" could lose their tax exempt status. It turned out that when financial interests conflicted with the Word of God, the fine scholars at BJU looked again and discovered God was totally cool with interracial dating after all.
This is very simple: if you believe same-sex marriage is sinful, don't get married to someone of the same sex. But if you believe your religion empowers you to seize basic civil rights away from other people who have nothing to do with you by the way
, that's not piety. You're just an asshole.
