Thirteen years passed between the Brown decision and Loving v. Virginia, the 1967 Supreme Court decision striking down bans on interracial marriage. "A large majority of supporters of racial integration and even nondiscrimination in the workplace did not believe that interracial marriage was tolerable," Professor Eskridge said. "In race, the marriage issue was the very last form of discrimination struck down." If the comparisons are apt and the same judicial timetable holds, that means bans on same-sex marriage will fall around 2016.
