I think I am going to embarrass a woman in my class
What would you get out of it by embarrassing the person?
I want to make fun of her in public
You should not want to do that, it is mean! You should not intentionally use a public space to embarrass others.
She needs to be humiliated and that is what I will do.
Have you ever thought that the person that does the humiliating will be condemned by others as being mean and rude? It might backfire on you, and I don't want that to happen to you because you are my friend. I don't want to see you get in trouble for humiliating someone, whether they deserve it or not.
