AITB for not taking my therapists advice?

Recently I have been seeing a therapist to improve my self esteem and correct my behavior. Her methods have been working so far and my mental health has vastly improved. However, she recently gave me advice that set off red flags in my mind. She lectured me on the importance of hating an action rather than a person. The examples she gave were hating rape and murder rather than hating a rapist or murderer. She then applied this to my toxic and abusive mother and said I should hate the things she has done to me but I should not hate her as a person. Then she made me repeat that to myself. I hated that exercise and i eventually stopped seeing her.

Is it just me or does her advice seem wrong? I felt it was out of line of her to tell me not to hate my mother for what she’s done. Or am I just too stuck in my ways?

Update: here’s some more context - I haven’t really talked about my mother other than me disliking her. I haven’t even really talked about why I don’t like her because I want to focus on myself and what I need to fix rather than fixate on how she’s affected me. Not that she hasn’t, just that I felt focusing too much on her impact would cause me to stay too focused on the past rather than moving forward. Because of this I felt it was out of line for my therapist to say anything because I haven’t told her the specifics of the situation or my past. And because I don’t really talk about my mom I thought it was strange for her to tell me to not “hate” her as a person - I’m not really thinking about her other than knowing I don’t want a relationship with her.

Thanks for the good advice and input so far! It really helped me look at this from another angle!

As for the therapist, I won’t be seeing her again as this wasn’t the only reason I wanted to stop seeing her, neurodivergency-wise, she didn’t really understand how to help me. 🙂
