From Salon.com:
The last time the president of the United States marked gay pride month with anything official at the White House, it was June 2006. George W. Bush decided to throw the weight of his office behind a proposal to amend the Constitution to ban gay marriage. After all, the fate of Western civilization hung in the balance. "Our policies should aim to strengthen families, not undermine them," Bush said at the time. "And changing the definition of marriage would undermine the family structure."
On Monday, 40 years and a day after the Stonewall riots began to bring the gay rights movement into the mainstream, Barack Obama took a slightly different tack.
