Religious extremism as we can see doesn’t only affect non religious people or atheists, but more often than not members of even the same religion but under a different sect would fall under these attacks.
So when one talks about the dangers of religion, it would be dangerous to think the consequences only apply to outsiders. Often the oppression religion wroughts falls more on its adherents, especially women and children.
Gunmen on motorbikes attacked a bus in the Pakistani city of Karachi, which was carrying members of a Shiite sect. In the Sunni dominated Pakistan, Shiites often come under attacks, despite the fact that they’re all Muslims.
