Meanwhile, the economic impact of same-sex marriage legalization is estimated in the billions over the next few years.

"There are 1.4 million LGBT business owners are the country - imagine how many more will come out now that the tide of equality has risen so hight," a National Gay and Lesbian Chamber of Commerce spokesperson told Fortune in a statement. "But marriage is not the finish line; it's the starting pistol. The 2014 buying power of LGBT America is $880 billion -- the community's loyalty can't be overestimated."
