So they have a self-loathing because they feel guilty for being 'advantaged' while the terrorists are 'disadvantaged' (poor), you know, they attack us because we have and they don't and surely we somehow robbed them to get it. They do need the victimhood and martyrdom, but will come to love us on the left only if we recognize our faults and join them in their misery. Which we won't.
A few of them might come to see our side, usually after being victimized by those they pity, but then those are lost to the lefties and loathed by them as well. To them, we are mean-spirited (sorry, I hate that term) and this gives them just cause (b/c they have no valid other one) to hate us. And they do hate us when we fight back. Any excuse, really.
