This isn't rational. It's just elitist snobbery. You can use the exact same structure of argument with respect to anything:

Aw, you got raped? Well who told you to go into a room with your friend without a handgun on you? Didn't you know you should be prepared to kill every man around you in case they turn on you?

Structurally identical.

It's an ideology of knives in the dark, the screams of the dying and enslaved, and the blood red light of fire on steel. Those who honestly endorse its underlying principles would just as happily endorse any barbarism on the strength of the defeated's inability to escape it, provided it went on at some suitable distance from them.

Why not be honest and sum up the only real thing it says? - Vae victus.
