The facades of the U.S. missions in Seoul and Chennai, India, are partially hidden behind large rainbow flags, while the embassy in New Delhi is aglow in rainbow colored lights. The website for the embassy in Santiago, Chile, shows a video of the chief diplomat raising a rainbow flag last month for the International Day Against Homophobia, Transphobia and Biphobia.

The Vienna Embassy's website features a photo of a rainbow flag flying below Old Glory on a mast jutting from the building, a statement by Diplomats for Equality and a story about a professor lecturing on the visibility and growth of LGBT rights.

U.S. diplomats in Jerusalem joined a March for Pride and Tolerance, and several ambassadors have tweeted photos of themselves in local Pride parades or standing outside the embassies surrounded by employees holding up letters spelling PRIDE.

"This is a category one insurrection," said one diplomat, who like others interviewed about the sentiment over the rejections, which were not made in writing, spoke on the condition of anonymity for fear of being fired.
