Anytime an adult makes use of the power that he/she has over an innocent child to inculcate ideas and practises which the child is neither old nor mature enough to understand that is abuse.

Have to say I agree with the others. That is a very sweeping statement. One of my greatest pleasures, these days, is being able to teach my grandson about spirituality, books, music, learning, nature, etc. all from my point of view, sanctioned by my daughter and her partner and greatly enjoyed by my grandson. I've done this since he was two days old and he is a remarkable four year old at this point showing no signs of abuse.
