AITA For telling my 13-year-old sister that she's the reason she doesn't have friends?

In a family where brilliance is both a blessing and a curse, Nora’s sharp mind cuts deeper than just intellect—it isolates her in a world she deems unworthy.

Her arrogance, born from a rare gift, erects walls between her and those she labels “intellectually inferior,” even turning cold toward her own sister, whose achievements only fuel the divide.

Caught between pride and frustration, the older sister watches as Nora’s brilliance becomes a barrier rather than a bridge.

Their parents’ unwavering defense of Nora’s superiority only deepens the chasm, leaving the family trapped in a painful struggle between love, acceptance, and the harsh sting of alienation.

Internet Users Didn’t Hold Back:

Users didn’t stay quiet — they showed up in full force, mixing support with sharp criticism. From calling out bad behavior to offering real talk, the comments lit up fast.

The original poster (OP) is grappling with the ethical dilemma of confronting their younger sister's severe arrogance and intellectual condescension, which is actively reinforced by their parents.

The core conflict lies between the OP's belief that teaching respect and empathy is crucial for the sister's future, and the parents' insistence on shielding the sister from criticism to preserve her sense of exceptionalism.

Given the family dynamic where the sister's negative behavior is excused as a byproduct of her intellect, is the OP justified in voicing a harsh but necessary truth about character over competence, or did their direct confrontation const*tute bullying that undermines necessary parental support?
