Creating a hate account on non muslim

So I used to watch this youtuber’s vid she is a non Muslim but spoke up about Palestine , now she is dating a trumpie and reads books from Zionist authors so all that support for Palestine was a show , can u make a page on TikTok for her exposing her and telling ppl her truth so she loses followers as Muslim we shouldn’t be supporting such people, she was like a comfort YouTuber so this lowkey feels like personal betrayal so will I get Gunnah for hurting her feelings and is this haram
