I was indoctrinated in the Southern Baptist faith and was 27 when I escaped. That crazy belief system and culture damaged my intellectual growth, inflicted guilt, stole happiness, wasted time and energy, imposed prejudices and much more.
I recognize that currently, almost everyone is indoctrinated into some belief system and culture. Every cocoon must hang from some tree and so every one of us comes to consciousness within some culture. Most cultures have crazy components to it. (Catholic: birth control abortion divorce, infallibility of Pope----Mormons golden book, magic underwear etc) A key question is whether you can break free and construct your own value system. Regretably only about 20% of us do so.
I believe we should stop indoctrinating our children. I think it is possible to teach values without doctrines. Here's apoem I wrote years ago:
I say to my readers: If you have escaped your indoctrination---created your own value system--you are a part of life's solution. Congratulations. If, on the other hand you believe the doctrines your parents told you---you are likely part of life's problem.
