Let's not start pinning this on every Muslim though. Why do they need to be out in the street to distance themselves from these arseholes? Who helped to create ISIS in the first place? Where did the arms and support come from?
Well... ISIS are claiming to be
true Islam, wanting to establish a caliphate. If you are a muslim, and think ISIS is the
wrong Islam and do not wish to be associated with them, then of course you should distance yourself from them. We have a foreign-hostile party here that claims to be true "Swedes and Swedishness", as I don't agree with them of what their version of this is, I distance myself from them personally and politically, as do many others, to demonstrate that their way is not the only way. If we just sat tacitly by, saying/doing nothing, against people who claim to
represent me, that would be tantamount to passive agreement.
ISIS claims to represent muslims, if muslims disagree there's an onus on them to say so. No one else can do it for them. If they want people to see the peace-loving side of Islam, speaking up is imperative. I've studied Islam and islamophobia, I've both read and spoken to and about muslims about various issues of their portrayal in media and the like, but at the end of the day I'm not a muslim, I have no authority to say "hey, ISIS, you guys are wrong! I've read in this book, heard from this person, that Islam is not how you paint it!" Only other muslims can truly take that stand.
Of course one cannot, in practice, do as I've done here which is treat "muslims" as a homogenous mass, which they are not, but distancing the issue from non-ISIS muslims is not realistic. That is not to say of course that muslims are the only ones who should protest, of course not, but they are intimately connected to ISIS through religion, whether they want to be or not.
Also, start voting... honestly, that's a very broad brush to paint with and is suggestive that people havent been voting against carnage before...? I think very few voters in your "US and Allies" group actively wanted anything like this to happen and probably believed they
were voting against it, or voting for the best way to manage it in
their opinion. The idea of voting as a powerful tool is delightfully charming, and it's not without importance of course, but the political power structures will never be fully swayed by voting, there are far too many players on the scene for it to massively affect the situation in the Middle East by now.
