Joining The Islamic State of Insanity

What kind of people are these? I saw the distraught husbands on the news:  "British police weren't much closer Wednesday to finding out what exactly has become of three sisters and their children, all of whom are believed to have left England to join their brother in the territory of the Islamic State of Iraq and Syria (ISIS).
A lawyer for the three women's husbands says there was no evidence of extremism, but CBS News correspondent Charlie D'Agata says their brother is thought to be fighting with the extremists in Syria, and the men fear their 12 family members have gone to join him.
It is a plea and a narrative that has become all too familiar in Britain.
Akhtar Iqbal and Mohammed Shoaib fear they may already have lost their wives and nine children to ISIS."

"No evidence of extremism"? That's a laugh. It's as much a lie as "Islam is the religion of peace".
