Harry Potter fans! Do any of you find it annoying that people call them children's books/movies?

I mean seriously, with all the violence and killings in it, does it really make sense to call it a childrens book? Its for teens and Y adults. Theres some cursing and ual content, and drinking. People think its a kids book because the main characters are, but these "children" are 17! In the 7th book, the are about 12 characters killed, some by stabbing or other non-magical causes. theres effing and two types of b words the trio drinks alcohol i believe and the romance and snogging? Plus they abuse children and cut and beat them, torture, and more. And I'm not some overreactive parent I'm 14, and i find this annoying because if they stopped calling them childrens books, then the movies wouldnt be so dumbed down and less mature, because despite the fact their labeled pg-13, parents bring 5 year olds anyway! since WB knows this, they make everything less serious than it is, so they can make money. I just think its unjust to call this series for kids as if its the magic tree house books
