Warded Ms. MacDonald/Mr. Malfoy.
I cannot pretend to understand whatever hurt or discrimination you have faced, Mr Malfoy, but I know what I have experienced. At the hands of a Slytherin. I don't believe what he did was a sad reaction to him facing some sort of discrimination by Dumbledore. So I suppose without knowing each other's journey we cannot - and should not - argue about this. But I will discuss this further with you to better understand your point of view.
Also, as far as your son is concerned, how do you know for sure your son will be in Slytherin? He could be in Ravenclaw. We cannot be bitter about things that haven't yet come to pass.
