ABA Therapy and PTSD

I was called “unethical” by a professional colleague today.
The reason may surprise you—I said “ABA is abuse”. My peer was naturally taken aback because they are an SLP-BCBA and “would never dream of abusing a child.” I always find this rebuttal interesting because we usually don’t hear about people walking around admitting to abusing people; even overt predators somehow convince themselves that they are helping their victim. The sanctimonious SLP-BCBA told me that it was the “old ABA” and not “new ABA” that was harmful, and then only a small fraction of the time. She accused me of “throwing the baby out with the bathwater” (I still don’t really understand how this idiomatic expression applies here) and she further went on to insist that there is “no way ABA could cause PTSD in people with Autism.” (She really meant “Autistic people,” I am sure.)
