I'm going to laugh at a girl who talked about rape in english class. It was so funny.
Why would you want to laugh at her?
It was such an idiotic thing to say and it makes me insane.
It's wrong to laugh at people just because of an opinion they hold. Have you thought about talking to her to see why she feels that way?
Why I should do that?
Because it's good to get a better understanding of someone's opinion. You might also learn why they said what they said.
