It isn't a new problem, but in this age of marriage equality and growing progress, it's surprising that the number of LGBT youth being kicked out of their homes is actually growing. An estimated 40 percent of LGBT homeless youth leave home because of family rejection.

This story in the recent Rolling Stone gets to the heart of the matter:

After what felt like an eternity, her mom finally responded. "I don't know what we could have done for God to have given us a fag as a child," she said before hanging up.

As soon as the line went dead, Jackie began sobbing. Still, she convinced herself that her parents would come around and accept her, despite what they perceived to be her flaw. As planned, she drove to Canada to celebrate her birthday with friends. When her debit card didn't work on the second day of the trip, she figured it was because she was in another country. Once back in the States, however, she got a call from her older brother. "He said, 'Mom and Dad don't want to talk to you, but I'm supposed to tell you what's going to happen,'" Jackie recalls. "And he's like, 'All your cards are going to be shut off, and Mom and Dad want you to take the car and drop it off at this specific location. Your phone's going to last for this much longer. They don't want you coming to the house, and you're not to contact them. You're not going to get any money from them. Nothing. And if you don't return the car, they're going to report it stolen.' And I'm just bawling. I hung up on him because I couldn't handle it." Her brother was so firm, so matter-of-fact, it was as if they already weren't family.

From that moment, Jackie knew that she was entirely on her own, that she had no home, no money and no family who would help her — and that this was the terrible price she'd pay for being a lesbian.

Jackie's story may be distinctive in its particulars, but across America, it is hardly unique. Research done by San Francisco State University's Family Acceptance Project, which studies and works to prevent health and mental­health risks facing LGBT youth, empirically confirms what common sense would imply to be true: Highly religious parents are significantly more likely than their less-religious counterparts to reject their children for being gay — a finding that social-service workers believe goes a long way toward explaining why LGBT people make up roughly five percent of the youth population overall, but an estimated 40 percent of the homeless-youth population. The Center for American Progress has reported that there are between 320,000 and 400,000 homeless LGBT youths in the United States. Meanwhile, as societal advancements have made being gay less stigmatized and gay people more visible — and as the Internet now allows kids to reach beyond their circumscribed social groups for acceptance and support — the average coming-out age has dropped from post-college age in the 1990s to around 16 today, which means that more and more kids are coming out while they're still economically reliant on their families. The resulting flood of kids who end up on the street, kicked out by parents whose religious beliefs often make them feel compelled to cast out their own offspring (one study estimates that up to 40 percent of LGBT homeless youth leave home due to family rejection), has been called a "hidden epidemic." Tragically, every step forward for the gay-rights movement creates a false hope of acceptance for certain youth, and therefore a swelling of the homeless-youth population.
