Well, I can see where you are coming from (although I think actually you missed my point, but never mind).
I don't think transition is as black and white as smacking. I think a non-medical, accepting approach to a gender questioning child (I.e. maybe supporting social transition) could be helpful to some children, especially ones that are very oppositional.
I think part of the problem we have is the research isn't there to show if social transition is harmful.
So I think saying that social transition is "profound abuse" is stretching the narrative somewhat.
One cannot reduce a topic like transgenderism down to a one sentence "transitioning children is profound abuse".
Does it mean 4 year olds? Or 17 year olds?
Does it mean medical transition, or using preferred pronouns?
Does it only refer to medical professionals or does it refer to everyone who engages with a "trans child" in their preferred identity?
I'm sorry, but I don't think a parent choosing to support their non-binary daughter by calling them xie/xir (or whatever) is "profound abuse".
