I remember how you twisted my words in your own thread about this dave.
Twice.

Derrick, IS do not rely on mainstream media to inform their audience of their killings, they broadcast their own slick hi-tec propaganda over the internet.
Those with an interest do not believe or trust the mainstream media anyway.

Dave,
So, obviously no decent person would join this organisation or continue the killing. Just young Muslims...

No decent person would join in the beheadings, crucifictions, burnings, sex slaving, ......
Or do you think that decent behaviour Dave?

They are not all young. A recent British family who went included people in their 70s.

Anyone who was not a Muslim would be put to death as soon as they arrive, so yes they are Muslims, but some are recent converts.
Ethnic white British. They are said to be among the most fanatical.
