My professor constantly inserts her political views into class discussions, and it’s becoming irritating as she clearly demonstrates bias toward one side, I’m not going to sit quite and listen to it anymore

We recently had a group project on illegal immigration where we were tasked with arguing the pros and cons, one of my teammates made a false statement about a political figure and picked it as a topic. I emailed my professor and asked her if we should change it, but she deemed the topic acceptable. I don’t understand how a professor can allow students to use misinformation in their arguments. Am I overthinking this? I know I’ll get attacked in class but idc I’m not going to allow her to try and flood my brain with false info
