I want to deface the books at the library so badly!
Why would you deface library books?
These books teach some orthodox stuff that's irrelevant for the modern age. People need to change their point of view or they will suffer in life.
You should never deface things at the library. The library and the people there are there to try to help you.
So you are telling me that schools should stay in the dark ages.
No, I'm saying that it's not your property to destroy possessions like that. Libraries in fact keep us from the dark ages, because there is just so much information and knowledge contained in it. You should try checking out random books, what you will learn there is countless.
