(AP) Gov. Bruce Rauner has signed a bill banning therapists from trying to change a young person’s sexuality. The Republican approved the so-called “gay conversion therapy” ban on Thursday. His office didn’t immediately offer a statement. The measure keeps therapists from trying to change the sexual orientation or gender identity of a person younger than 18. Providers who don’t comply could face disciplinary action. Supporters of the measure have argued conversion therapy has been discredited and can be harmful to young people. But opponents have questioned whether therapists would be punished unfairly and say a ban limits parents’ treatment decisions.
