Agreed, but there may be an under-lying reason for this. People tend to point out things that they see as weaknesses, that’s true enough, but they do this because they see the strength there to “fix” the negatives. We, as living beings, tend to focus on the weaknesses because that is what will get us hurt, killed, raped, taken advantage of, or make us “lose the race.” We are taught to develop ourselves through criticism. The approval and encouragement should be there, though, and it is hard for parents to find the balance with the kids at times. When I see a weakness in my children, I do point it out, but I also give them comments on how well they have done in other areas. I am told that I am too critical, but there is that reason again. I see the potential for them to develop stronger qualities, and also understand that if they do not, then they are vulnerable.
This is why the media and all other “spin” masters are so successful. People are drawn to conflict because it reminds them of their own faults, their own failures, and their own weaknesses. They are reminded of just how vulnerable they are. So, it’s not always a bad thing. People just need to be taught to see all of the incoming messages as being both constructive and deconstructive at the same time.
(Hope that all made sense.)
