So I came across a friend's post on Facebook talking about Weird Al's 'Word Crimes' song and how they consider it one of Weird Al's "meanest songs in a long time". Specifically pointing out (they are a linguist) the line "you should hire some cunning linguist to help you distinguish what is proper English". They feel that the song talks down to people, specifically that it's calling out ESL or International fans as if we should all learn and speak proper English and that we fault you for not being able to (I am paraphrasing).

Now, English is my first language and I don't speak other languages very well so I believe I'm taking the song in it's original intent which is to make fun of the evolution of language, specifically on the Internet. However, how do you take the song and it's meaning? Is it mean?
