Why Islamic extremist sites should be cracked down on

The question is what can an avg person do in his personal capacity? Mosques in general have been talking against extremism in friday sermons. How does an individual crackdown an extremist site…assuming one even knows the url for some crackpot joint type of website aside from reporting it to authorities, who probably have more resources at their disposal to track those type of sites down anyways.

does everyone know everyone at a mosque or everyone in their community, do they know what someone is upto at all times, or who that person associates with?

so when you say people do absolutely nothing, what would you like them to do? All someone really should be doing is making sure that he does his best to keep his children, siblings and friends grounded in reality.

coming back to the topic of this thread, yes extremist sites should be banned, but that is something that authorities can do, not Uncle Afzal who goes to Brooklyn Masjid and works as a tax accountant for macys.
