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.
