Nice post, I think many people stop fighting after driving the darkness out of their own lives and that is the "blinded" affect you referred to.  Personally, I try to think of us all as one, so if some of us still suffer or struggle, collectively we all do.  I always got caught up on the idea that I'll never make major change happen, but now I try to think about it from a collective standpoint, so all positive change we make collectively progresses humanity and hopefully in the end we win.  Just my thoughts after reading.  :)
