This happened to me before
What I did to fix it was, when I see something political, just scroll as fast as you can. Don't even pause it to look in the comments. Every second you engage with it tells Instagram to serve you more of it. So just scroll. And if there's something you like, watch the entire video so Instagram gives you more of that. I did this and my feed was back to skits and extreme sports in literally 20 minutes
