Not at All Dear Vernon Dursley,
I hate you. Did you know that "stomping the magical nonsense", as you put it, out of a child could seriously injure both the child in question and yourself. Not to mention that said child had a genocidal maniac intent on killing all non or half-magical people out for his blood. Harry saved you despite how horrible you were to him. Even if you won't admit it, he saved your life. I wish you a long life of pain and regret. Also, when you went to the zoo, why didn't they keep you?

Dear Glambert Goddess,
Do not write to me ever again! Don't you dare interrogate me on my methods of trying to protect my family from this magical madness! If anymore letters come to my door from you or from any of your magically-obsessed lot, they will be going straight in the fire where they belong!
DO NOT WRITE HERE AGAIN
-Mr Vernon Dursley
