IS has declared war on the "Poofters", the punishment for their disgusting unholy habits is cheap and effective:-
Take 'em on to the roof of a high building and "Sling 'em orf".
They have a choice and if they don't take it, that's their own fault, the choice is a simple one:-
Get out of the country and go and live in some place like America or UK where they can even marry each other, well, if the practice is good enough for the Clergy, Politicians and even Royalty in those places, it's good enough for everyone else who lives there.
It is NOT acceptable in the Holy and respectable lands under the protection of Allah the merciful, it's just not on you see.
