<human>: Can you summarize the given text in a few sentences?

I'm researching terrorism in graduate school.  A thesis topic I'm considering is the willingness of individuals to report suspicious activity of their peers.

For example, if you were a fundamentalist anti-abortion Christian, and you noticed some of the members of your congregation became more militantly anti-abortion, would you report it?

I'm curious as to whether individuals would consider reporting their friends for violent extremism, even if they agreed with the logic behind the violence.  Examples: Anti-government groups, Pro-Succession groups, Racist groups, Radical Islamists, etc.

Since Reddit is such a diverse community, I thought it would be interesting to see what you would produce.  Has anyone here reported someone they considered dangerous?  (Share privately if you're concerned about sharing publicly)
<bot>: Would you report a terrorist, even if they were a friend/family member?  HAVE you reported people you know to the authorities for dangerous behavior?  Please share your story.
