I mean in my opinion even if hootaloo's therapist is telling him what he wants to hear (which I really doubt) hootaloo himself says that it has helped him and he it isn't harming anyone else so I don't see a problem.
I know a guy on steam that struggles with dysphoria and he's in a country that isn't too kind to trans people so he can't actually find anywhere that will take him seriously and it results in him being really sad most of the time.
