Ann Romney, wife of GOP presidential candidate Mitt Romney, on Tuesday lauded her “real marriage” during her keynote speech at the Republican National Convention taking place in Tampa.

“I read somewhere that Mitt and I have a 'storybook marriage,'” she said of her 43-year marriage. “Well, in the storybooks I read, there were never long, long, rainy winter afternoons in a house with five boys screaming at once. And those storybooks never seemed to have chapters called MS or breast cancer. A storybook marriage? No, not at all. What Mitt Romney and I have is a real marriage.”

The comment prompted the Human Rights Campaign (HRC), the nation's largest gay rights advocate, to launch a tweet campaign to remind Romney that the marriages of gay and lesbian couples are also “real.”

“Lesbian and gay couples feel the same love, honor and commitment the Romneys feel for each other,” the group wrote. “Thanks to marriage equality legislation, couples in six states and D.C. are able to celebrate their own 'real marriages.'”

HRC encouraged members to tweet the following message to Romney: “Because of #marriagequality, my same-sex partner & I have a #realmarriage too, @AnnDRomney.”
