I just noticed that while it’s common for witches to marry muggle men, wizards seldom or never marry muggle women. Think about it: Dean Thomas’s mother is a witch and his father is a muggle. Andromeda Black (witch) marries Ted Tonks (muggle). Voldemort’s mum (witch) marries handsome Tom Riddle Sr. (muggle). Snape’s mum (witch) marries alcoholic white-trash fellow (muggle). Hagrid’s mum (giantess) marries non-magical non-giant man.
Can anyone think of an instance where it runs the other way? And, if not, am I forced to conclude that witches are somehow naturally more muggle-like, or, in a word, weaker?
