California Outlaws Gay Conversion Therapy

I don't care much about this one way or another--I think sexual preference is largely fixed fairly early on, but malleable to some extent that varies from person to person. I think we'd all be better off if people generally felt freer to be who they are more-or-less naturally. But I also understand people who prefer to have more average/normal sexual preferences, and I don't think it's my business to tell them they can't try to accomplish that if they want to. Though, again, personally, I'd say: try to be happy with who you are. I'm told that "gay conversion therapy" doesn't work--which wouldn't surprise me.
   But question: are all treatments that don't work outlawed in California? How about woo-woo "New Age" crystal-rubbing? Past-life regression? Homeopathy? Acupuncture? Ordinary old faith healing / prayer? Any of the zillion other magical pseudocures? Are they all at least banned for minors?
   Or is this being treated as a special case because it's something that the left hates?
