Good solid story, why the language?

I liked the book and what drawn by the title and
'Booklist's' review comparing it to Heinlein's Coming of Age Books. Wish the crude language which toned down tho. Coming at this as a teacher and fan of 'coming of age' books to use with my students, I really liked the jabs at the education system, the idea of ​​taking learning and education in your own hands and growing up. Looking forward to the next one .... but my hope is did you realize the book can stand on its own without that kind of language. It Seems to be stuck in there 'Because it's a book for teens'. It will be fine without it.
