Maybe her fame is bringing much needed attention to these kids and their cause. Hopefully that would be the positive that comes from her involvement in this line of work.
On another note, someone made a comment about Angelina's arms. If some people think her arms are grotesquely skinny, can you imagine how the arms and legs of the children she sees on her travels look like? That must be beyond sad and horrific. Many of these little kids have disfigured bodies from disease and starvation and those protruding stomachs they get from malnutrition.
