I was told by my professor that I was reported for making a misogynistic joke in class. I have no idea what I said and it's really not like me, since I know we have a student that I gets offending by everything, esp white males.

They refused to tell me what I said even though I told them I can't be held responsible for what I said when I had no idea what it was what offended someone. It's nuts that I get in trouble for something I don't remember saying and they refuse to tell me what I said.

I know who it was, the class isn't large and like I said she gets offended easily, I was warned prior to starting class. Why does she get away with stuff like that when she offends me I just let it go? Why doesn't the professor say something to her when it's obvious she is attacking white males in class?

TL:DR Joke gets me in trouble, have no idea what I said.
