There are a number of authors you might want to check out to learn about islam: Robert Spencer, Danial Pipes, Ibn Warraq, Bat Y'eour, Craig Winn...also a number of websites to get you started: www.answeringislam.org, www.jihadwatch.org, prophetofdoom.net, faithfreedom, etc.
Thanks for those. I was just telling my hubby that we should do some research. This will really help us get started.
