I agree that it implies a complete lack of understanding of what being raped is.
Let me help you with this one.
rape
n.
1. The crime of forcing another person to submit to sex acts, especially sexual intercourse.
2. The act of seizing and carrying off by force; abduction.
3. Abusive or improper treatment; violation: a rape of justice.
tr.v. raped, rap·ing, rapes
1. To force (another person) to submit to sex acts, especially sexual intercourse; commit rape on.
2. To seize and carry off by force.
3. To plunder or pillage.
So care to explain how reading a book 'raped your childhood'?
Did it abduct your youth?
Or force your innocence into an unwilling sexual act?
Or were you trying to sound clever?
I guess what you meant was that you lost a little innocence by reading something that you were not mature enough to deal with.
By the way, the above post was mee having a little fun by answering how I Imagine covenant may have answered himself.
