Would you ask your daughter to take down a picture if it bothered your parents

My daughter is 19 and really into cosplay and anime and things like that. She reads so many mangas. She posts her cosplay on Facebook and Instagram. My parents have both. They had an issue with her most recent cosplay. My parents are pretty religious and they found her cosplay offensive. She posted this picture and said "Confessions of a Rotten Girl" and she was cosplaying as hatsu Miku. She's cosplayed at her many times. What bothered my parents was she was holding a paddle that said "sinner". I'm not sure why she. Idk if she was trying to be a sexual hatsu Miku or what she was doing with that but my parents found it offensive and want me to ask her to take it down. I feel awkward doing that.
