A wise post! I've seen a lot of people and friends getting into this trap of having tons of information/ knowledge available through the internet and blindly believing. But the point is, that information is almost always selected towards a certain direction. Let's take the vaccines for example. Yes, there are cases of Autism eventually caused by vaccination. But we don't know the exact details: the individual circumstances, the genetic disposition, the amount of vaccines a patient receives at once and so on. Unless we get into original clinical trials, we only know just a part of a fact. A differentiated thinking instead of interpreting emotionally would bring more clarity..
