Hi. So I (15F/M) have a sister ‘Cecilia’ (13F). Cecilia and our uncle have had a long history of arguing. Not only is our uncle racist, but he is also a bit transphobic to me in the past especially, and a misogynist who used to beat his ex-wife and current wife whenever he was angry, which he claimed was because of the medication he was on/alcohol, IDK.
One day, he tried to ask Cecilia to get him back with his ex-wife who already has a husband and a kid. However, Cecilia said no. He called her a traitor, she blocked him, and he told me to “tell Cecilia fuck you”.
Our grandma, however, the Mom of our uncle and dad, told Cecilia she should apologize and “admit her wrongdoing” so they could be a whole family again.
Is Cecilia TA for refusing to apologize and not forgiving our uncle?
My vote, but this is me: NTA.

Am I missing something? Who asks a 13-year-old to help him get with a woman who is married with a kid? Make that make sense. Until then, NTA.
Also, a 13 year old is never to blame for fucking up the family. Chances are the family was fucked up before the child came along. No offense. You seem alright. I mean the people victim blaming the child. Sounds like something between gaslighting and grooming.
