Sixto Cancel says his ultra-religious foster family frequently talked about their disdain for his homosexuality at the dinner table, trashed his room and called him homophobic slurs. While he was still a teenager, he says, they kicked him out of their Connecticut home after he had lived there for nearly a decade. "I've had foster homes who completely said you can't live here if you're gay," said Cancel, a 21-year-old student at Virginia Commonwealth University who bounced between half a dozen foster homes while in care. "For a long time I had that self-hatred and uncomfortableness with who I am." Discrimination against gay and lesbian youths in foster care is prevalent enough around the country that federal health officials sent a letter in 2011 encouraging states to develop training for caseworkers and foster parents on the issue. Advocates in a handful of states including Florida, California, Connecticut, Illinois and Massachusetts have increased efforts to train caseworkers, recruit foster parents and assign mentors.
