AITA for punching my friend after she kept comparing my favorite characters to hers

And calling them copies of her favorite characters/her favs in another life, she's been like this ever since we met, every single character I like she compares with hers. She either one ups them or downgrades them as copies. Just a few minutes ago I was talking about how I liked GenShuLin from Wuthering Waves and she suddenly cut me off and showed a twt post of someone saying that GenShuLin looked like Till and said "OMG GENSHULIN LOOKS LIKE TILL SO HES MINE NOW BACK OFF" and some other weird annoying shit so I punched her.

Just kidding. I didn't. But I wanted to.
