Its the self-destructive nature of the Primitives. Drug use, poor decisions have ruined their lives. Their behavior has got them cast out by their families. Primitives feel abandoned.
I hesitate to use a line from the LOTRs, but like Gollum, they hate and love themselves.
DUmmies transfer that hate onto what is good and true. Christians and Jews are truth and good, so they must be hated. Patriotism is good, that must be rejected. Those who abandoned the DUmmies are guilty and all they hold dear is now rejected by DUmmies.
islam is false, it is not a threat for them. Like Weiner, DUmmies will excuse all islam's crimes. I think the DUmmies are enamored of the freedom to kill your enemies in islam.
In short. DUmmies have chosen evil over good, and have no defenses against the lies of evil.
