Recent gay rights victories have failed to eradicate homophobia, Michelangelo Signorile is expected to argue in his upcoming book Beyond Tolerance.

According to the AP, Signorile's book will be published by Houghton Mifflin Harcort in 2015. Beyond Tolerance is the book's working title.

The 52-year-old Signorile, a gay rights activist with his own SiriusXM radio show mostly devoted to LGBT issues, has four books under his belt, including Queer in America, Life Outside, Outing Yourself and Hitting Hard.

In Beyond Tolerance, Signorile – who has devoted a large portion of his career to the issue of how to fairly report on closeted public figures – will argue that despite winning federal marriage recognition, homophobia persists in America.

It's been a big year for Signorile, who married historian David Gerstner in New York City in July and appeared in gay glossy Out's 2012 Out100.
