Your description couldn't be farther away from the article you linked. My first thought based on your description was that this was going to be an article about some youths here in the U.S. who in some way were engaged in, or threatening in a physical way, some seniors desire to be heard or speak their mind on some religious issue.
This article is about young women who live in an oppressive culture (for them) reacting in a violent way to that oppression. You call it free speech by a senior. Well, in this situation the mans age really has zero bearing on what took place. Additionally there is no such thing as free speech in their culture. Everyone has to be mindful of what they say publicly, the women even more so than the men. These young women will in all likelihood suffer greatly for their actions. Were they wrong to do what they did? Absolutely. But to paint it as a misguided youths abuse senior citizens and prevent them from voicing their religious views and their right to free speech is a bit over the top.
All that aside I wonder where this next generation of youth in these Islamist countries are going to take things. I'm not talking in the next 5 or 10 years, but beyond that. When the children being born now reach their 20's and 30's. While I don't even know anyone personally who is Islamist I look at people I know who are Jewish, Catholic, and various other Christian denominations and I see what appears to me as a lessening devotion to their religion in the younger age groups. I see a lot of migration from more traditional churches to what I call the Holistic or Organic churches. The very loosely affiliated Unity churches come to mind. Churches where body, mind, and religion were intertwined or equal parts in their teachings (Chakra, reiki, or chanting anyone ).
Is anyone familiar enough with Islam to share some insight? I feel like Islam and most of the countries where it is the primary religion has not evolved or caught up with its worldly counterparts. Where society and religion might be called archaic in these countries compared to the modern or advanced U.S., Canada, U.K, Australia, etc.
