So are you saying that when I watched those shows my subconscious brain knew I was being taught Illuminati? The brain can only sort out things it knows. If it sees a symbol that relates to Illuminati then it doesn't file it under the Illuminati category when it has no knowledge of Illuminati. As for acting on what is being watched I have many times acted on shows I have watched. I have become a super hero among the Justice League. I have lived in Bikini Bottom with Spongebob as my neighbor. I have become a wizard with Harry Potter...actually I have become Harry Potter.(Oddly enough when that came out the kid on the book looked like me. I wore circular glasses and had a scar on my forehead, not in a lightning bolt though) My point is I have acted on many things I have watched(emotions too). Guess what though. I was using my imagination and nothing more.
Also, last I checked children have some of the worst attention spans which is why most shows are fast paced. Not many children will watch something that takes forever to progress. That is why many shows have failed, well that and the fact that they were just horrible and not in the least bit funny, interesting, etc.
Though, going on your post, if your child reacts badly to one show then don't let them watch that show. As long as they can still tell the difference in right and wrong and know what reality is I see no problem.
The symbolism is more about invoking something spiritually. You are thinking about it in a physiological sense. Harry Potter supports sorcery. I will look up some scriptures on that if you would like for me to. The whole Illuminati thing is probably fake, but you can't deny the fact that occult symbolism is being displayed in just about every cartoon and movie out there, repeating the same symbols over and over. To deny this fact is foolish because there is overwhelming evidence supporting it. If you look into occult and how it is practiced, it is very symbolic and ritualistic. People can be cursed through certain practice and the fact that these symbols that are used for occult ritual and casting spells and conjuring spirits is in a child's cartoon should be enough to concern any parent. If you don't believe supernatural or spirit realm exist, or that people can use it against other people through occult practice, then you are mistaken. I know the concept of spiritual warfare is so vague to a lot of people that it is hard to fathom that demonic and angelic presence could really hold any kind of influence on us at all, but it always begs the question - how can you believe in Jesus Christ, but not believe in these things?
