Answer:
Beck would call this statement an example of "dichotomous thinking" or "black-and-white thinking."
Aaron T. Beck, a pioneer in cognitive therapy, identified this type of thinking as a cognitive distortion. Dichotomous thinking involves viewing things in absolute, all-or-nothing terms, without acknowledging the shades of gray or complexity in between. The speaker is labeling the person as being either entirely with him (doing everything to help him) or entirely against him (not caring at all), without considering that the person's actions or feelings might be more nuanced.
