one of the lessons* of this spree killing is people who traffic in eurabist fantasy consider eu states to be "fallen" and their white populations "lost". they have no qualms about murdering white people in furtherance of their political aims. begging people still complacent about eurabism to get a fucking clue, especially white people thinking it doesn't affect them. it does.
(*not much of a lesson, this is far from the first far-right political mass killing primarily targeting white people in the last 20 years and definitely won't be the last. some people will point out a paradox. there is no paradox. white people murdered by falangists cease to be white on the point of death, do yourself a favour and read some Eco)
