Latinos in the War/Jena Six

I wasn't really aware of the whole "not letting Latinos be part of The War documentary." It seems ridiculous to try and leave a group out of a documentary about a war in which they helped to fight. I don't understand why people like to segragate themselves and others from different groups. I thought that with the civil rights movement any type of racism would have calmed down by now, but what I have learned in the past few days, I can see that is not so.
For example, recently, the Jena Six scandal has made headlines nation-wide and there's no doubt in my mind that this has to do with race. Jena is a small town in Louisiana in which the population is approximately 85 percent White. The six young black men are looking at a lot of time in jail for getting into a fight with a young white male who was sent to the hospital with multiple bruises. There are things that happened prior to that incident, like the hanging on nooses on an all-white tree and then three of the Jena Six fight to try to get away from a guy who had them at gun-point.
From watching the YouTube videos from Democracy Now online, the white people interviewed from Jena don't think all these incidents have anything to do with race at all. It is astonishing to think of how oblivious these people are to what is really going on. It is a small town and I guess it is easier for racism to exist, but I can't believe there are those kind of people out there still.
It is sad to see that racism still exist in the world today but I guess it will always exist, even in its smallest form, in the smallest towns.
