Then why in all those years has none of your crack team of Kind People come up with a definition of “conversion therapy” that would make this unambiguous?
Or even identified a single practitioner of this thing you want to outlaw.
We can name a whole bunch of people doing dodgy things that should be stopped, although whether the law is the right method is debatable. Various Republican US states are busy using the law to try to stop children being given puberty blockers or surgery - they at least can point to it actually happening, and you can see those involved in it kicking up a fuss.
But for this one, we have a bunch of perfectly responsible therapists worried it will be fuzzy enough to hit them, some vague reassurances that "oh, of course it won't", but no demonstration of who it is supposed to hit apart from them.
