My only advice is be careful with what you watch, and with the amount of trust you put in it. We know very well that the media usually shows the things the way THEY wish, and not the things as they actually are. Im pretty sure everybody already noticed that the same news is reported in different ways by different tv stations, or newspapers, or whatever. And sometimes the difference is enormous. If they do this with facts, that can be "physically" proven, much more they can do with theories, or histories, or whatever that be less "concrete" than facts. So, they can manipulate it to almost any way they wish, and so convey any thought or idea they wish under any disguise they think appropriate. And most people will watch it and accept is as it was stated, without bothering to think about how it could have been distorted, changed or altered in any way by the media presenting it.
So, take everything you watch on tv (or read or whatever) with a grain of salt (at the VERY least). Cause who knows how true it actually is?
