You are probably unaware of just how subtly we are subject to propaganda.
The "others" are always the "bad guys" and we are the "good". Actually, the truth is somewhere in between. Many times in history we have been the "bad guys". Remember we are subject to propaganda as well, although we may not realise it.
The answer is get your data from multiple sources, often with radically different ways of seeing a situation. In reality, the truth is an amalgamation of inputs from various sources.
Don't believe at face value what you are being fed in the news.
