Please help me, I don't know what to do!!!

We were having a round-table discussion in my scripture class today & the topic came up about surrogate motherhood. The way my teacher explained it made it sound like a child who's born that way is the result of a terrible sin. I mentioned that Blanket was born by a surrogate mother because she made it sound like he was the spawn of sin. Well, she clarified everything for me, but then she went so far as to say that Michael Jackson is not someone to uphold as a role model & that he will be judged for his sins. ( bear in mind that those weren't her exact words but I think it's what she meant). I felt so insulted by that & on top of it all, the whole class started laughing! She insulted me & humiliated me in front of everyone. & not only me, but she insulted Michael as well. I wanted to cry, but what good was that gonna do? I wNt to do something about it but I have no idea what. Please help me!
