You infer offense—none was intended. I am speaking factually.
Based on what knowledge or evidence? If you mean the simple meaning of 'indoctrinate', then you missed the mark because your post came across quite offensive, whether meant or not.
There is nothing wrong with indoctrination as long as it adheres to the truth of one's belief. And the song 'Jesus Loves Me' is, as I state, a simple song letting children know of Christ's love. Teaching them to sing it, if indoctrination, is the purest form of teaching the truth. Yet you make it seem offensive.
