Having read a few earlier posts on this thread, the general thrust seems to be KILL them.
NOW personally, I don't think these IS attacks have ANYTHING TO DO WITH ISLAM.
Islam is no more violent a religion than Christianity is.
NO. NO --
IS is not being run by religious believers... There MAY BE some demented souls who THINK they are speaking for ISLAM, but they are NOT.
IS is a haven for PSYCHOPATHS.
They are drawn in like foxes discovering a henhouse. They seek destruction and anarchy, NOTHING MORE.
TO BLAME all Muslims is simply an act of ignorance, and proposals to kill them ALL is a similar psycho response.

No winners there friends.
THIS whole issue is not about religion. It is about power.
If Islamic terror has nothing to do with Islam why did Qadri need 600 pages for his fatwa to outlaw Islamic terror?
