Blinded by their rage

It appears that the mad Mullahs are being warned about warned about self harm. No, not the obvious in that they have woken up large sections of the European public as to the unreasonableness of their brand of Salafic extremism, though that is undoubtedly true. Nor indeed the bringing to the fore of many moderate Muslims who have with perseverance and courage stood up the fanatics. No this advice is more practical.

The Welsh flag maker, Mr Flag, has issued a warning to the fanatics,
""We have experienced a rise in orders for the Danish colours," owner Robin Ashburner confirmed.
But he warned, "It has to be pointed out though that a number of modern flags are now made largely of polyester and when they burn they melt. That means if they are whirled around by a protester, his or her fellow protesters could be splashed by flying pieces of burning material. If it got into the eye it could do serious damage so we are about to issue a warning to this effect on our website.""

Indeed here is the warning
"For safety reasons we don’t recommend that you burn our flags, but if you absolutely MUST, please do so with due regard to those around you. Polyester fabric melts when put to the flame and will spatter high-temperature droplets of molten polyester if swung around."

That such a thing might happen, blinded by their own rage perhaps?
