It`s not "white people" telling "Black people" what to do and it`s not "ethnicity" who "judges" people.
It is always individual persons who judge or not and each one may have a different point of view not depending on their skin complexion. When we talk about racism or sexism it is a problem within societies and concerns society as a whole and every single one of us who we are part of it. It is a misconception to think of people as "groups" in terms of opinions or actions.
Yes, we can create groups for sociological statistical analysis, like income groups, gender groups, ethnicities, etc. yet they are a concept, not a reality (i.e. they are not homogenous), and any discussion about "them" is subject to interpretation.
Not everyone here may like that thought, but things such as a "Black Nation" or a "White Nation" do not exist in real life.
It would be ridiculous to think of a billion of individuals living in different countries and continents, in different law systems, in different communities, and being part of different denominations and "walks of life" as a "homogenous" group or at least a group with some invisible magical string that would bond them together, just because they happen to have approximately the same color shade on the outside, or have ancestry that happend to live in the same climate zone about 10,000 years ago.
Our opinions are not related to our color or sex. i am a white man, but very often have to agree with things a Black person or a Woman has said here on B2w, on other forums and "in real life".
