This is an example of a logical fallacy; specifically, begging the question. It assumes the conclusion in the premise
It is not a given that disciplining a child is a sign of parental alienation in the long-term.
Disciplining a child (whether physically or otherwise) does not inexorably cause parental alienation. My parents disciplined me, both with spankings and by grounding me or taking away privileges. This made me unhappy, but did not alienate me from either of my parents.
It is possible for a parent to engage in excessive and/or inappropriate child discipline that will have the effect of alienating the child from that parent or (eve more tragically) from the innocent parent, but it is not a given that mere discipline of a child causes parental alienation.
