Appearing this week on Fox News' Fox & Friends, psychiatrist Keith Ablow criticized an Obama administration directive on transgender students.

The Justice and Education departments advised schools that receive federal funding to allow transgender students to use the bathroom of their choice.

Ablow, a strong opponent of LGBT rights, called the directive an “overreach” by the federal government.

“I think this is a huge overreach by the federal government which essentially would give them de facto control of all schools in America forever in every way,” Ablow said on the program. “What if the federal government, Barack Obama were to say 'Listen, there are people who find in their identities – they identify as younger. When they would normally graduate high school, if they say, 'I'm really still more like 15 or 16,' you must keep them in school.' Well, why can't we leave this to the states to deal with rationally?”

“Identity is not reality,” he added. “These are questions of identity. So when the president seeks to apply this and say, 'Look, we've made a decision. When somebody says that they're female, they are.' Hey, that's not settled from a medical standpoint, psychological standpoint, or any other standpoint.”

Ablow, a regular contributor to Fox News, in 2011 warned parents not to let their children watch ABC's Dancing with the Stars because Chaz Bono, a transgender man, was competing that year.
