Why is it that holocaust deniers and violent thugs who threaten people with death are always to be "understood", the victims' faults, real or imagined, to be paraded as the "root cause" of the holocaust deniers violent thuggery -- but only when they are Muslims?
If you're going to go that route to justify holocaust denial and terroristic violence, please, let's do it for all groups. I want you, DC, to "somewhat understand" the Ku Klux Klan's terrorism and hatred. Surely you agree some Blacks did horrible things to white people, and that therefore we must consider this "root cause" before we "mindlessly" condemn the KKK?
In reality, such demands for "understanding" and "investigation of the root causes" are, de facto, merely excusing such behavior and blaming the victims.
