So in your mind this all boils down to who is the most heavily pigmented, Wolfgang?

Promoting racial hatred (which is what you are involved in doing), by cynically using the victimization of one group of people (in this case people you are calling "Black") for the purpose of spreading hatred towards a second group of people (the ones you are calling "Arabs"), in service of a political agenda that is not in any way humanitarian (which is what the government of some Western countries and Western media are doing), is racism.

If you are genuinely interested in what is best for the Dafurian farmers, you won't participate in what these people are doing. Because the end result of all of this pressure on the US government to take action will not be good for the farmers. They will still get cleared off of their land. And many, many more of them will die in the process. All you have to do to know the truth of this is to see what is happening right now in Iraq.
