Do you think it's wrong that I always give hot chicks worse grades?
I hope you're just kidding. Why would you give them worse grades?
I don't like the hot chicks and I'm punishing them for being so pretty.
It is wrong to give grades out based on how people look. Their grades should only be based on their performance in class.
But they have it easy enough already.
I don't think it's fair to them that you're basing grades on something as arbitrary as their appearance. Everyone should be graded the same way, based on how well they're able to do the work.
