I have noticed this throughout my life, even being too nice (as I often am) is regarded as weakness by many others even though they would not even realize what they doing.

We are still a primitive species trying very hard to pretend we are not. Finding the strengths in other instead of weakness takes effort by a lot of people, an effort they will not even attempt in most cases.

If mankind is around for another 1000 years maybe things will change for the better.
