It's your fyp. I haven't noticed a single thing that people have been complaining about.
Make absolutely certain you do not interact with videos you don't like. No commenting, no checking the comments, no liking, no sharing, no looking at the creators page. Hit not interested and move on.
In the past week I've been told or have seen people complaining that tiktok is full of provocative dancing, right wing extremists, instagram memes, no leftist or progressive content, racism, and brain rot.
My fyp is animal videos, content about the games I'm playing right now, music I enjoy, and progressive comedians. Occasionally I get a video of a local protest against the current US administration or a pro labor post. I haven't seen anything like that you're describing. Occasionally it tries to serve me "young people romance drama", I click not interested, it goes away.
