As an example: Religion is an opinion. It is held by many people, BUT NOT ALL. If a religion appears, is put to scientific scrutiny, and proved viable. Is it still a religion, or does it become science? And if every man, women and child participated in this religion, wouldn't the word itself be obsolete? Every one would have the same beliefs, based on science. It's called secularism. You don't need to blindly do anything. If I question science, I'm welcome to do so. So indoctrination is impossible, because I can question anything at any moment. Let's just agree to disagree here. I am starting to feel like I'm beating my dead horse now.
