Yeah, slightly confusing post...but...
You're using the reasoning concerning potential impact on the wider world as a reason for focussing on Pal, not Darfur or global indentured labour, as a primary campaiging issue - basically, there isn't enough time to reach out to every cause in the world. But you're reasoning is exactly that used by the mainstream global media for ignoring those issues - and that is based on a hierarchy of what's classified as news importance for a local audience.
So I say again, there is a selective process on whom to support, based not on who is most in need of support, but on who can shout that they need help the loudest.
