You are welcome!
I am well aware of intention to import heroin into more and more areas, yes - although I have to say that I know about it from non muslims from the poppy growing regions. I think that agenda is just as much driven by greed as it is by any kind of religious ideals or motive.
I have spoken with a man from the Yazidi tribe, yes, you are correct - the extremist groups there are literally operating a culture of enslavement, murder and torture that makes 'mad max' look tame.
The issue of what is truly in the Quran and other texts is not straightforwards to those who do not speak arabic and I know from my own experience that attempts to get to the truth of the situation had led to significant arguments about translations by various groups involved. Some claim there is absolutely nothing in the texts which justifies barbarism, while others say the opposite.
There is also the concept of Taqiya within Islam which may be used to justify totally lying about Islam to outsiders. So in a sense, we literally need to learn Arabic to get to the truth here.
