Also seems the guy who killed all the victims is a far righter and possibly extremist if you'd do some further digging.
I bet Oberyn's response to that would be something similar to this:
Totally justified actions as the glorious nationalists of Europe have grown tired of the multiculturalist supporting, zionist loving scum of Europe and this is the result of the filthy immigrants flooding our fine European master race nations (that are also rich with western cultures that these filthy immigrants won't ever comprehend and adapt to) and thus have also made the proud nationalists of Europe enraged and they won't take this multiculturalist bullshit anymore. Long live Napoleon, Charlemagne and European supremacy
(Also insert tons of links to far right websites covering rape statistics of European nations and also end the post with a ''Anti-Racist is a codeword for anti-white!'' and ''Asia for Asians, Africa for Africans and Europe for EVERYONE'')
