How do you respond without sounding mad?

If it were written by a woman I'd be mad because I'd know it's a real opinion and she's retarded, but because the review was written by a man I assume he's joking and probably just not cut out for philosophy or perhaps a bit young for it and was forced to read it for a class, so I don't feel too mad. But if a woman had written that, oh boy, I'd be hopping fucking mad right now. God I hate women so much.
