Many excellent web sites discuss Islam. But unfortunately, for those people just now starting to pay attention to this concern, perusing these sites is like coming into the middle of a movie. It's difficult to know who's doing what to whom.
There is a new site called Islamic Threat Simplified. It is the starting place for facts on Islam without the spin of political correctness. There is a wealth of information, dozens of links to Islamic experts and an excellent glossary of terms.
Check it out. Share it with friends who are just now getting concerned.
