No they can’t “fuck you up permanently” that is just conspiracy nonsense. Their malpractice is the lowest of any that practice medicine. Why? Because it’s minimally invasive and nowhere near as dangerous as a medical doctor incorrectly prescribing the wrong medication.

And a lot of the spinal manipulation techniques are being adopted today by physical therapists because they see the scientifically based advantages. Stop spreading disinformation.
