Legislation which seeks to ban therapies that attempt to alter a minor's sexual orientation from gay to straight was introduced in Michigan last week.

According to MLive, the measure is being backed by Rep. Adam Zemke, a Democrat from Ann Arbor.

“The evidence shows you cannot change sexual orientation, so the legislation was kind of a no-brainer,” Zemke said. “We want to make sure children cannot be exposed to situations that are emotionally harmful to them because of their parents' beliefs or desires to try to change their orientation.”

The proposed legislation is modeled after California's first-in-the-nation law. A similar law was approved last year in New Jersey. But efforts in Illinois, Ohio, Pennsylvania and New York have been blocked or stalled.

Republican Rep. Gail Haines, who chairs the House Health Policy Committee, has already signaled his opposition to the bill, calling it “unnecessary.”
