I have two issues with the banning of conversion therapy:
Firstly, I remember reading stories of people that went thru the therapy and stated that it helped them live the satisfying lives that they already waned to live. In at least one case, a man who had been a practicing homosexual ended up marrying (to a former lesbian, no less!) and beng a father. If it helps even one person be what he/she be what he/she wants to be it should not be banned.
Banning the therapy is potentially a violation of free speech. ( re:https://www.washingtonpost.com/religion/2019/02/02/judge-says-tampa-conversion-therapy-ban-violates-first-amendment-free-speech-rights/
