I have clicked on your three links with pictures. For two of those links there is no way to tell whether the people portrayed are Janjaweed or not. But the third (first) photo comes with a text. Did you read it, Carol? I did and I laughed about this part:

Nope. I didn't get past the caption, which says, A Janjaweed on the back of (his) camel. The Sudanese government has supplied to the Janjaweed horses and camels.

I did a google image search and used pictures that were captioned as being people who were Janjaweed. To see the picures in their original contexts, do a Google image seach on the key word, Janjaweed.

Here in the US, all of the people pictured and captioned as being Janjaweed (that I found) would be considered by others, and would consider themselves Black.

This tells us nothing about Black people, just as the fact that they speak Arabic tells us nothing about Arabs. What is sinister is when people try to convince others that what is going on in Sudan has anything whatever to do with anyone being "Arab" or "Black".

Just how are people defining "Arab" anyway? And how are they defining "Black"? These are pretty arbitrary classifications under the circumstances, and they are being used in service of an agenda that has nothing whatever to do with human rights or the prevention of genocide.

The rebels are killing civilians, too. But we don't ever hear about that in the news media (at least not the news media in the country in which I live). Why is that?

The reason is because the agenda being served by both sides is that of clearing the people off of the land. The people who support the rebels want the people cleared off the land just as much as the people who support the Janjaweed do. The only difference between the agendas of the two sides is who each side want's to have control of the land once the people are cleared off of it.

The government of Sudan wants to control the land after the people are cleared off of it, and the people backing the rebels want to have control of the land once the people are cleared off of it.

In the final analysis, that's what it all boils down to.
