ISIS actually doing terrible and inhumane things for their own promotion and to intimidate opponents.
Unfortunately, it seems that this strategy works for them.
Every day they have more and more followers among young Muslim people in the western world are and this is a serious security problem for western democratic world now.
This is no longer just a war against an insane criminal and terrorist organizations, but also the war for the survival of multiculturalism in the West.
If Western democracies do not stop this ideological and multicultural conflict between west and east, this will cause even greater divisions and conflicts in the future and it will then be the defeat of Western democracy and multiculturalism.
The west have already lost on multiciulturalism front. Only the most indoctrinated leftists and liberals don't see how that failed.
Democracy... well, a representative democracy is barely a real democracy at all, I'd say what we have here is an oligarchy with some (disintegrating) make-up. It would be time to try something new (or old if suits better.)
IMO a conflict with muslims in Europe is inevitable, and this kind of democracy, multiculturalism and PC going to seal our fate.
