Good questions. I got answers, baby!
I think you are right ingesting and injecting morals is like injecting bleach. Yeah bleach cleans those stubborn stains out of your favorite shirt, but it won't clean out your colon. It will just kill you.
Also, people really tend to forget that the world is under a giant filter we love to call media. We crave the spin media puts on everything like a crack head on W. 142nd Street. We all should go cold turkey and get our knowledge from books, not the news. Cheers.
