The we progress as individuals, the more we gain self awareness.
Naturally, when humans see differentiation on a large scale, it's their natural instinct to feel threatened. This has been an evolving concept that man has carried in his right hand since the dawn of man. Today, (and please exclude MBTI completely from this) when humans see differences, they automatically come to attention and it goes back to our natural instinct to either change it or attack it. (and yes, yes, I know about the J's and the P's, this is on a larger scale though.)
now, does anyone understand what I'm saying? or am I just completely wrong, and have wasted my time explaining this phenomenon?
