Conversion therapy causes more harm than good. There have been documented cases of non binary sexuality in humans for thousands of years, and all animals have a spectum of sexuality. Trying to force what is natural into two caragories only alienates and causes mental harm to those individuals. Conversion therapy doesnt truely change feelings, only hides them so deep that the person can feel like they're not there anymore.
There are so many (generally young) people out there who would benefit from banning converaion therapy, and focusing on harm reduction therapies instead.
