Are there any legitimate, "general" areas needing improvement by some culture groups?

If so, what, and how can there be improvements? NO DEROGATORY REMARKS, PLEASE! Some groups often see things from "their" perspective, & therefore fail to understand why people have any negative feelings towards them. This leads to anger & cries of discrimination as an instant response, I believe. However, I feel that a fresh, honest outside look at oneself can shed light on why people get feelings that reinforce discrimination. Is there something that you perceive as negative, "in general", yet legitimate, about your own race, ethnicity, culture, etc.? Can't helping us see/face & improve our own areas of faults/problems help how others view us as a group and therefore reduce discrimination / animosity ? PLEASE,...stay civilized, MATURE & CONSTRUCTIVE.
