ISLAMICS is a quite recent site reacting to Christian discussion of Islam.
ISLAMICS displays in particular responses to Dr. Robert Morey. We do not necessarily agree with all of Dr. Morey's writings, but we are commited to fair comparison and discussion. ISLAMICS does only give Muslim rebuttal texts, but does not link to Dr. Morey's articles.
Material by Dr. Morey: , , 
And they also link to responses to Jay Smith (at a site which in turn doesn't link to Jay Smith's papers), which can be found at The Debate Site
Interestingly, they are listing under "Responses and Replies to Missionaries" also the "Response to the Atheist Manifesto" as if any missionary would be an atheist. Somehow they are a bit confused.
