Well its factual because you know if you picked up the Quran or Read Reliable Hadith it doesn't support any of this.....
It's a bit like saying "what do atheists think of school gun deaths?" America is predominantly atheist. Therefore it's an atheist problem. It's not really helpful to just say "it's not an atheist problem".
I'll just go back to what I said before, like G-MAN2004 pointed out it's also factual that Muslim communities are predominantly affected by it irrespective of any direct link to Islamic literature.
The problem is that serious issues within those communities will never be solved while ever people like you start screaming about Islamophobia whenever someone sees the link between forced marriage, honour killing and child sexual exploitation primarily existing within the Muslim community and tries to go in those communities to fix it. If it's nothing to do with Islam then there shouldn't be any resistance to government education programmes going into Mosque's etc to try to educate adults against such cultural practices but lets face it if anyone tried there would just be a huge **** storm about Islamophobia and so things will never change.
