NEW YORK, Feb 6 (Reuters) - New York state will bar health insurance coverage of therapy aimed at changing the sexual or gender orientation of young people, Governor Andrew Cuomo said on Saturday, decrying the practice as "misguided" and "intolerant." Top U.S. health officials have long discredited so-called "conversion therapy," saying attempts to change lesbian, gay, bisexual and transgender (LGBT) youth are unethical and often harmful.
