So, I'm a third year student studying mathematics. My goal has always been getting a PhD in math. I'm currently doing ok with my math (taking grad courses and stuff). However, as many other students, I have to take courses outside math. I'm currently taking a labor studies class right now. All the class talks about is how bad America is treating its workers, and why don't we raise minimum wage to 50 dollars per hours to help the poor workers and stuff like that. I don't agree with everything I learn in class, and I show my disagree. As a result, the professor gives me terrible grades for saying my opinions. My question is: Will that bad grad hurt my future? Can I explain my situation in my application?
