The fight against a controversial therapy that purports to "cure" gay people of their gayness and make them straight has come to New York. The therapy has been around for decades, but has come under increased scrutiny in the last few years as gay rights supporters have argued it doesn't work and may cause great harm to those who undergo it. Over the past several years, the entire mainstream mental health community has renounced it, and politicians in several states have taken steps to restrict it. New York's legislation, which will be introduced on Friday, is modeled after a new California law that bans licensed therapists from using the practice, sometimes called conversion therapy or sexual orientation change efforts, on minors. California's bill, the first of its kind, was signed into law last fall and is currently on hold while a federal appeals court considers two lawsuits alleging an unconstitutional violation of free speech and parental rights.
