AITAH for calling out someone who kept replying rudely to my comments on Kim Sae Ron’s profile?

Hi Reddit. I (15F) have been grieving the loss of Kim Sae Ron, who passed away 5 months ago. About a month ago, I posted a comment on her MyDramaList profile saying:

It was a passionate comment about how she was unfairly treated during her life. I’ve already posted condolences before, and I wanted to take a moment to speak to the haters instead.

A much older user (she states she’s nearly 70) responded a month later with:

I was offended and replied, asking why I should talk about Kim Sae Ron on someone else’s profile (she implied I should go to Kim Soo Hyun’s). She has responded to several of my previous comments rudely, always with a condescending tone.

I privately messaged her explaining my comment and my religious context: as a Muslim, traditional “rest in peace” phrases are not used for non-Muslims, so I express condolences differently. I said I still respect and support Kim Sae Ron in my own way. I also asked her not to keep calling me out publicly since I’m just trying to support someone I admired.

She never responded to my DM, but later publicly replied to my comment again, saying this would be her "ONLY TIME" responding to me, accusing me of harassment and trolling, saying:

I responded calmly, clarifying again that I was not trolling, just explaining my intentions. I mentioned how she's repeatedly replied to me and other users with similar aggressive tones, which makes us feel like we can’t grieve or defend Kim Sae Ron in our own ways.

Now she’s completely ghosted me, but I feel frustrated. I tried to be respectful in private and explain myself, and she made it public and twisted it.

So AITAH for pushing back on someone who kept replying to my comments publicly and being aggressive, when all I wanted to do was support a late actress I loved?

By the way, this is really summarized, there was more to what she had said.

Extra context:

• I’ve never mentioned Kim Soo Hyun in any of my comments, though others have.
• She told another user to go post their anger “on his profile” too.
• Her MDL bio says she hates bullying, yet she replies rudely to fans all the time.
• I'm a teenager just trying to grieve and speak up how I can.
