apartheid, walls, race, class and borders/boundaries

While I haven't seen the movie, the coffins displayed upon this wall as well as the graves being marked with piles of rocks looking like the cairns I grew up following on Appalachian mountain footpaths struck me. I was recently told by a professor that I was making work that was too conservative. That scared me. Now I realize I cannot shy away from what I have to say,
While I question the use of McCain soundclip speaking of knowledge of the human heart, this film looks like an interesting investigation of the absolutely murderous intentions of those behind this hugely expensive wall separating land from itself. Political boundaries are so fixed in our minds, but why? They are won through stealing and wars, and maintained in ways such as described in this videoclip. While Israeli apartheid week was taking place a week or so ago, I found myself wondering about the US version of the wall, different, so very different, but somehow much the same...
