[Harry Potter] Why didn’t Percy ever give Malfoy detention for saying the word “mudblood”?

Hogwarts doesn't seem to have a rule explicitly forbidding that kind of language, and if it does, it's likely that Percy would avoid punishing Malfoy for something that Lucius would argue is him abusing his authority to push his father's own pro-muggle agenda.
