What's your point of stoning and terrorism ? why you're mentioning it here ?
It seems to me that I will inevitably have to restate my argument, so here it goes:
1) The OP made the claim that the terrorists who carried out the Paris attacks were not practicing Muslims.
2) I responded saying that a lot of the members of ISIS and Al-Qaeda are indeed practicing Muslims (like bin Laden himself, whom a lot of Muslims consider a hero, at least where I live), and that tens of millions of Muslims supported things like stoning, lashing, and killing homosexuals, which was made evident in their voting choices when they voted for fundamentalist (Islamist) parties that had a particularly harsh interpretation of Shari'a.
So I'm mentioning these things to respond to the OP, who seems to be arguing that "true" or "practicing" Muslims can't be violent.
If you are inclined to, I recommend looking up
Hazem Salah Abu Ismail in Arabic. Just read some of the comments on articles mentioning him and listen to his own words. This is a man whose pictures were lifted up high in Islamist demonstrations where over a million people gathered in a public square in Egypt. He refused to call bin Laden a non-believer and said "May Allah have mercy on him." Millions of Egyptians support him. Actually, I just asked my older brother whom he would vote for president if he had the free choice to. He said, "Abu Ismail."
I think I know well about the two countries I've spent my entire life in, FearGod. I'm not some stranger who is making arguments out of the blue; this is stuff I have been researching, reading about, and listening to stuff about for years now. I struggled with it as a Muslim and wanted things to be different, but they are what they are. I guess we just don't share the same view of the Muslim world if you believe that most Muslims are moderate people who don't support anything violent like stoning or lashing.
