eh, i don't disagree, but out of risk of sounding like a conspirist, many things that seem scientific or factual, are often motivated by money, it takes money to do research, so the same rich people 1-2 millinea ago, are very much in control of what we are fed.
you can take the some what recent event of the george zimmerman thing, the media would say that he used a racist slur, every one would get worked into a frenzy, and few would even notice the retraction, because then we got the blurred surveillance video, you couldn't see the head wounds, until unaltered video was released, but that didn't matter, experts where saying the screems for help where TM, ofcourse their was something else to distract from other experts disagreeing. by the time the real evidence was presented in court, the country had largely come to the wrong conclusion, because it was more profitable for the news outlets to stir up half-truths...
we are flooded with modern moral values, that are ever changing, and often money driven.
